[webservices] ws-station and obviously wrong sensitivity

[Philip Crotwell]

Hi

One of our stations has an "unknown" sensor. I know that sounds weird,
but it is old, 50 meters down a borehole backfilled with concrete and
no records left from the installation. So, in order to get the data to
the archive, we had to submit dataless where the response was filled
in, but in a way that says "we don't know". Mary said that the correct
way to do this was a unity gain blockette53 with no poles or zeros. If
you have the full response, this is a pretty noticeable oddball. But
in the channel level of the station web service, you get just the
overall sensitivity. It is probably still relative clear that this is
bogus, but not quite as clear as it is the 1 from the sensor combined
with the actual gain from the digitizer, so you get something like
629129.0 for the sensitivity. As this appears to be somewhat of a
standard, it might be better if the station web service could tell the
difference between this type of "syntactically correct, but obviously
wrong" response and just not publish a value for those stations to
avoid sending out wrong values.

If you are interested, the stations with this issue from our network
are CO.CSB and CO.RGR.

thanks,
Philip
