Local Alternatives

ObsPy contains local alternatives to some of the calculation tools offered by the IRIS web services. Consider using them when working within ObsPy:

IRIS Web Service	Equivalent ObsPy Function/Module
`obspy.clients.iris.client.Client.traveltime()`	`obspy.taup`
`obspy.clients.iris.client.Client.distaz()`	`obspy.geodetics`
`obspy.clients.iris.client.Client.flinnengdahl()`	`obspy.geodetics.flinnengdahl.FlinnEngdahl`

Each of the following methods directly wrap a single Web service provided by IRIS (https://service.iris.edu/irisws/):

Request Tools

evalresp() - evaluates instrument response information stored at the IRIS DMC and outputs ASCII data or Bode Plots.
resp() - provides access to channel response information in the SEED RESP format (as used by evalresp)
sacpz() - provides access to instrument response information (per-channel) as poles and zeros in the ASCII format used by SAC and other programs
timeseries() - fetches segments of seismic data and returns data formatted in either MiniSEED, ASCII or SAC. It can optionally filter the data.

Calculation Tools

traveltime() - calculates travel-times for seismic phases using a 1-D spherical Earth model.
distaz() - calculate the distance and azimuth between two points on a sphere.
flinnengdahl() - converts a latitude, longitude pair into either a Flinn-Engdahl seismic region code or region name.

Please see the documentation for each method for further information and examples to retrieve various data from the IRIS DMC.
