Query the station service of the client. Bulk request.

Send a bulk request for stations to the server. bulk can either be specified as a filename, a file-like object or a string (with information formatted according to the FDSN standard) or a list of lists (each specifying network, station, location, channel, starttime and endtime). See examples and parameter description for more details.

Parameters:
  • bulk (str, file or list of lists) Information about the requested data. See above for details.
  • quality (str, optional) Select a specific SEED quality indicator, handling is data center dependent. Ignored when bulk is provided as a request string/file.
  • minimumlength (float, optional) Limit results to continuous data segments of a minimum length specified in seconds. Ignored when bulk is provided as a request string/file.
  • longestonly (bool, optional) Limit results to the longest continuous segment per channel. Ignored when bulk is provided as a request string/file.
  • filename (str or file) If given, the downloaded data will be saved there instead of being parse to an ObsPy object. Thus it will contain the raw data from the webservices.
  • attach_response (bool) Specify whether the station web service should be used to automatically attach response information to each trace in the result set. A warning will be shown if a response can not be found for a channel. Does nothing if output to a file was specified.

Any additional keyword arguments will be passed to the webservice as additional arguments. If you pass one of the default parameters and the webservice does not support it, a warning will be issued. Passing any non-default parameters that the webservice does not support will raise an error.
