Changelog

For better reproducibility, specific versions of ObsPy can be cited using the DOIs assigned to releases of ObsPy or ObsPy in general can be cited using a concept DOI (see Zenodo FAQ).

1.3.0 (doi: 10.5281/zenodo.6327346)

Changes:

• obspy.*

  • no more support for Python 2 (see #2577)

  • added python 3.9 and 3.10 tests for all platforms, minimal supported python version is 3.7 (#2925, #2489)

  • removed os.path calls with pathlib library calls (see #2751).

  • rewrote CI tests to make use of cache (see #2936)

  • removed individual logging configurations in Obspy, logging can be configured by the user, see documentation of Pythons logging module, only the FDSN mass downloader automatically configures logging as before, but this behavior can be turned off now. The loglevel keywords are therefore deprecated and have no effect anymore (see #2720)

  • refactored obspy-runtest to use pytest and modified several command line arguments, required to disable image comparisons (see #2489)

  • removed calls to deprecated NumPy functionality (see #2949, #2981)

  • cleaned the documentation, build process, and docstrings (see #2662, #2954)

  • refactored and modernized setup.py (see #2422)

• scripts:

  • SDS report: try to be faster on slow filesystems (see #3009)

• obspy.core:

  • speed up import of obspy core functions (see #2758)

  • read_inventory(): add “level” option to read files faster when less level of detail is needed. currently only implemented for StationXML reading (see #2759)

  • add option to suppress evalresp sensitivity mismatch warning when removing instrument response (see #2677)

  • round magnitudes in Catalog/Event string representation to one decimal (see #2742)

  • add support for pathlib.Path objects in read(), read_inventory() and read_events() functions (see #2743)

  • add a “DEF” option (default units) to Inventory.plot_response() and Trace.remove_response() (see #2806)

  • stream.select(): circumvent wildcard-matching when called with a trace-id without wildcards for quicker trace selection.

  • Inventory addition now consistently uses shallow copies (#2675, #2694)

  • removed obsolete wrapper around numpy.loadtxt causing import error with numpy 1.22 (see #2912, #2913)

  • fix iso8601 regex for issue #2868 to cope with day 360 properly

  • fix crash when resampling very short traces (see #2926)

  • response list stages: do not raise an exception if response calculation involves extrapolation outside of frequency range defined by the response list stage but rather only show a warning. raising an exception is the safe route but it also prevents valid calculations as it is up to the user to make sure that signal spectrum is properly suppressed in those frequency ranges outside of the valid response information (see #2988)

  • fix a bug while checking for valid URI syntax when setting identifiers on inventory type objects (see #2905)

• obspy.clients.arclink:

  • submodule removed completely, since ArcLink was officially deprecated and deactivated on all big datacenters years ago (see #2994)

• obspy.clients.fdsn:

  • introduce fine-grained FDSN client exceptions (see #2653, #2964)

  • support for “eventtype” parameter in get_events(), as specified in version 1.2 of the FDSN event web service (see #2780)

  • Hostnames with hyphens and long TLDs are no longer rejected as invalid FDSN server URLs (#2878)

  • add URL mapping for IRISPH5, IESDMC, GEOFON (alternative to GFZ) (see #2739, #2932)

  • update RESIF URL mapping to use http and add RESIFPH5 (see #2938)

• obspy.clients.filesystem:

  • add get_waveforms_bulk() method to SDS client (see #2616, #2626)

  • SDS client get_latency(): make one internal check optional which can be a massive speedup on slow filesystems (see #3009)

• obspy.clients.seedlink:

  • basic client: properly terminate after finished get_info() request (see #2996)

• obspy.imaging:

  • fix section plot in case of a single trace only (see #2764)

  • removed basemap, now only cartopy is supported for maps (see #2961)

  • fix day plot when passed a small interval (see #2967)

• obspy.io.kinemetrics:

  • adds the apply_calib argument to the read_evt method to allow obtaining the raw data bits stored in the evt file (see #2582), note this changes the default (wrong!) behaviour, by default the data returned will be the NOT corrected ones. When passing apply_calib=True, the calibration factor will be used.

• obspy.io.nordic:

  • add read and write support for New Nordic format (see #2814)

  • fix bug where negative magnitudes were not read properly

  • fix bug where empty hours / minutes / seconds were not read as zero

  • fix bug where lat/lon-errors were read as lon/lat

  • stop writing waveform-file link to a DUMMY-file by default

  • add support for I/O of apparent velocity / horizontal slowness

  • add support for writing of multiple origins

  • add event-type mapping between Nordic and Obspy/Quakeml (do not fully match)

  • fix a bug reading SEED blockettes 48 and 58 which was likely never encountered (see #2668)

  • Properly read a given value of 0.0 in station elevation and not replace it with bogus value (see #2763)

• obspy.signal.array_analysis

  • UTCDateTime objects can now accept hour, minute, second, and microsecond values greater than their normal limits by setting the strict keyword argument to False (see #2232).

  • Fixed UTCDateTime(…, julday=366) for non-leap years. This was returning January 1st of the next year in case of non-leap years being used. Now it properly raises an out-of-bounds ValueError (see #2369)

  • When reading StationXML/SC3ML, make sure to properly read empty string fields as empty strings instead of “None” (see #2519 and #2527)

  • Better ISO8601 detection for UTCDateTime objects and UTCDateTime(…, iso8601=False) now completely disables ISO8601 handling (see #2447)

  • Added replace method to UTCDateTime class (see #2077).

  • Added remove method to Inventory class (see #2088).

  • Added id property to WaveformStreamID (see #2131).

  • Adding more location codes to the default priority list in the mass downloader (see #2155, #2159).

  • The mass downloader now raises a warning if all channels from a station have been deselected due to the default location priorities setting. This is a pure usability improvement as it has been confusing users (see #2159).

  • Make sure that streams fetched via FDSN are properly trimmed to user requested times if data center serves additional data around the start/end (see #1887, #2298)

1.0.1: (doi: 10.5281/zenodo.48254)

• General:

      • obspy.io.xseed Parser objects (e.g. from dataless SEED file)

      • filename of a RESP file

      • dictionary with poles and zeros information (like in prior versions) Most old codes should still work, issuing a deprecation warning, but old code that specifies both paz and parser keywords will raise an exception.

    • Whenever possible (i.e. when using for metadata an Inventory, a Parser or a RESP file), response calculation now takes into account the full response (all stages) as opposed to only using the poles and zeros response stage (as was done in previous versions when using a Parser object). When using a poles and zeros dictionary response calculation is unchanged (as no information on other stages is available, of course).

    • PPSD now stores the psd for each time segment that gets processed, instead of only storing the stacked histogram. That way, differing custom stacks with various selection criteria (e.g. time of day, by weekday, etc.) can now be made from the same processed data (see #1130).

    • New save/load mechanism using numpy .npz binary format that circumvents some problems with the old pickle mechanism: PPSD.save_npz() and PPSD.load_npz() (and PPSD.add_npz() to add data from additional npz files)

    • Change default colormap to new obspy default sequential colormap (matplotlibs new viridis colormap). The old PQLX colormap is provided by obspy.imaging.cm.pqlx and can be used with PPSD.plot(..., cmap=...).

    • new option PPSD.plot(..., cumulative=True) for a cumulative plot of the histogram, i.e. a non-exceedence percentage visualization, similar to the percentile option.

    • x axis in PPSD.plot() can be switched to frequency in Hz with PPSD.plot(..., xaxis_frequency=True) (see #1130)

    • changes to special handling of rotational: now handled by kwarg special_handling="ringlaser" (kwarg is_rotational_data is deprecated, see #916)

    • special handling option for hydrophone data (no differentiation, see #916)

    • bin width on frequency axis can now be controlled using PPSD(..., frequency_bin_width_octaves=...) (in fractions of octaves, default is the old fixed setting of 1/8 octaves as in PQLX)

• obspy.taup

  • Added support for nd file format for input velocity models. Allows for named discontinuities at arbitrary depths allowing for less Earth like models (see #1147).

  • Added three methods (get_travel_times_geo(), get_pierce_points_geo() and get_ray_paths_geo()) to TauPyModel to handle station and event location data as latitude and longitude, instead of the source to station distance in degrees. In addition get_ray_paths_geo() and get_pierce_points_geo() decorate the returned pierce points and ray paths with the latitude and longitude of each point. Some functionality needs the geographiclib module to be installed. (See #1164.)

  • ObsPy now ships with a bunch of new velocity models in addition to the existing ones: prem, sp6, 1066a,b, herrin (See #1196).

  • Add support for buried receivers (see #1103.)

  • Port more accurate calculation of ray parameter from Java. The effect is stronger for longer phases, but also corrects issues with shorter body and surface waves (see #986.)

  • Fix incorrect branch splitting which also caused issues for extremely shallow phases (see #1057.)

  • Proper cache for model splits resulting in much faster calculations if the source depth is repeatedly the same (see #1248).

0.10.3: (doi: 10.5281/zenodo.46150)

• obspy.core:

  • Fix reading of multiple catalog files using globs (see #1065).

  • Fixed a bug when using Trace.remove_response(..., water_level=None). With that setting that is supposed to not use any water level stabilization in the inversion of the instrument response spectrum actually the instrument response was never inverted and thus instead of a deconvolution a convolution was performed (see #1104).

  • Fixing floating point precision/rounding issue with UTCDateTime when initializing with floating point seconds, i.e. with microseconds, that could lead to microseconds being off by 1 microsecond (see #1096)

  • Correct gap/overlap time returned by Stream.get_gaps() and printed by Stream.print_gaps() which was incorrect by one time the sampling interval (see #1151)

  • Stream.get_gaps(): return overlaps specified in units of samples as negative integers (see #1151)

• obspy.fdsn:

  • More detailed error messages on failing requests (see #1079)

  • Follows redirects for POST requests (see #1143)

• obspy.imaging:

  • Updated to libmseed 2.17.

• obspy.signal:

  • Bug fixed within rotate.rotate2zne(). Additionally it can now also perform the inverse rotation (see #1061).

  • Bug fixed in triggering. When using option max_len_delete and a trigger occurred right before the end of data, one trigger was potentially lost (see #1145 for details).

• obspy.station:

  • Plotting responses across multiple channels is more robust now in presence of some strange channels (e.g. with zero sampling rate, happens e.g. for state of health channels, see #1115)

  • ObsPy no longer assumes that the StationXML namespace is the default namespace (see #1060).

  • Checking if a file is a StationXML file is less rigorous (and much faster) now (not checking strict validity against xsd schema but only looking for a FDSNStationXML root element, see #1114). This means that read_inventory() without explicitly specified format will correctly detect more files as StationXML that have very slight breaches of the schema but still can be interpreted as StationXML.

  • added getInventory() method to the Parser object. Returns a dictionary about the contents of the Parser object. This is also integrated in the string representation and makes it more informative.

  • allow parsing of oversized VariableString from SEED, but warn and cut string to max_length at writing SEED (#701)

• obspy.mseed:

  • adding experimental details option, which extracts timing quality and info on the calibration

0.7.1:

  • adding ‘equal_scale’ option to plot() method

  • removing hash fixture for Stream and Trace

  • stream.select works now case insensitive

  • support for initialization of UTCDateTime from numpy.string_ types

  • new dtype parameter on read method allows converting data into given dtype

  • AttribDict may now be initialized with (key, value) kwarg pairs, e.g. AttribDict(a=1, b=2).

    • changed many setter/getter in UTCDateTime to private methods, e.g. _getDate

  • added UTCDateTime.DEFAULT_PRECISION

  • import of an unsupported waveform will result into a TypeError [#338]

  • added compatibility methods for AttribDict and UTCDateTime

  • retaining trace order in stream while merging
