[webservices] Earth-unit Conversion Issue with LDO/BDO Channel Data in timeseries product?

[Alex Jacques]

Hello Support,

Thank you for providing such a great suite of web service products, they
have been extremely useful for my research which examines the atmospheric
pressure data collected by the US Transportable Array (TA).  For my work,
the timeseries product has been immensely helpful, however I've run into a
bit of a snag over the last week when attempting to query data from the
LDO/BDO channels for the TA and N4 networks (pressure data from the Setra
278 sensors).  I'm able to query and see the "integer count" data just fine
as shown in the plotting tool example below...

http://service.iris.edu/irisws/timeseries/1/query?net=TA&sta=N63A&loc=EP&cha=LDO&start=2014.330T12:00:00&end=2014.331T12:00:00&output=plot

However, when I attempt to apply the instrument correction argument
(correct=true) to get the data into earth units, which is the actual
pressure reading, I receive an internal server error.

http://service.iris.edu/irisws/timeseries/1/query?net=TA&sta=N63A&loc=EP&cha=LDO&start=2014.330T12:00:00&end=2014.331T12:00:00&output=plot&correct=true

It appears that perhaps the internal conversion function is not
understanding the conversion string information properly, but that is just
a cursory look from my end based on the information provided to me from the
error display.  Would it be possible for someone to take a look at this?  I
do use other channels that contain atmospheric data as well (LDM/BDM for
example) and those appear to be working properly, I'm unclear on if this
issue is occurring with any other channels or networks.

Thanks for taking a look into this.
