- _write_slist(stream, filename, **kwargs)¶
Writes a ASCII SLIST file.
>>> from obspy import read >>> st = read() >>> st.write("slist.ascii", format="SLIST")
SLIST Format Description
SLIST is a simple ASCII time series format. Each contiguous time series segment (no gaps or overlaps) is represented with a header line followed by a sample lists. There are no restrictions on how the segments are organized into files, a file might contain a single segment or many, concatenated segments either for the same channel or many different channels.
Header lines have the general form:
TIMESERIES SourceName, # samples, # sps, Time, Format, Type, Units
- “Net_Sta_Loc_Chan_Qual”, no spaces, quality code optional
- # samples
- Number of samples following header
- # sps
- Sampling rate in samples per second
- Time of first sample in ISO YYYY-MM-DDTHH:MM:SS.FFFFFF format
- ‘TSPAIR’ (fixed)
- Sample type ‘INTEGER’, ‘FLOAT’ or ‘ASCII’
- Units of time-series, e.g. Counts, M/S, etc., may not contain spaces
Samples are listed in 6 columns with the time-series incrementing from left to right and wrapping to the next line. The time of the first sample is the time listed in the header.
Example SLIST file:
TIMESERIES NL_HGN_00_BHZ_R, 12 samples, 40 sps, 2003-05-29T02:13:22.043400, SLIST, INTEGER, Counts 2787 2776 2774 2780 2783 2782 2776 2766 2759 2760 2765 2767 ...
