Hello iris webservices,
Some of our queries to the fdsnws station service are returning nothing. This only happens for certain stations and certain time periods, and with matchtimeseries=TRUE.
For example this returns nothing:
http://service.iris.edu/fdsnws/station/1/query?loc=00&end=2014-09-10T09%3A47%3A11&sta=BJT&level=chan&matchtimeseries=TRUE&net=IC&start=2014-09-10T09%3A27%3A11
But this (without the matchtimeseries=TRUE) returns XML:
http://service.iris.edu/fdsnws/station/1/query?loc=00&end=2014-09-10T09%3A47%3A11&sta=BJT&level=chan&net=IC&start=2014-09-10T09%3A27%3A11
As does this (with matchtimeseries=TRUE, but 3 days earlier):
http://service.iris.edu/fdsnws/station/1/query?loc=00&end=2014-09-07T09%3A47%3A11&sta=BJT&level=chan&matchtimeseries=TRUE&net=IC&start=2014-09-07T09%3A27%3A11
Does this lack of results mean that none of the channels have data for the time period selected? Is this a bug or expected behaviour?
Regards,
Matthew
