Hi Barry,

The BUD web tools site does appear to have a bug, we'll look into it.  =
This is an IRIS interface and has nothing directly to do with the USGS =
who contributes much of their data to the IRIS Data Management Center =
(DMC).  For future issues regarding those web pages please email =
comments@....................

Also, those BUD web tools are (mostly) functional but somewhat =
antiquated, there are other options to get data from specific stations.  =
For example, the IRIS DMC's web services can be used to access most =
data, metadata or events managed by the DMC including near real-time =
data.  While these are technically programmatic interfaces, we do have =
simple web interfaces, Perl scripts, a Java library and a MATLAB =
interface that gets data from the DMC's services directly to a users =
computer.

Here is more information on our web services:
www.iris.edu/ws/

Each service has a main overview page with a link to a "URL Builder", =
which is a web interface designed for exploring how to use service and =
also works well for "one off" data requests.  As an example, here's the =
"URL Builder" for our ws-timeseries service:

http://www.iris.edu/ws/builder/timeseries/

The ws-timeseries web service, in addition to extracting data from our =
archive, is able to apply basic time series processing to the data =
before delivery.  The processing includes things like filtering, =
instrument correction, conversion to SAC and ASCII formats, etc.

While the IRIS DMC is primarily funded to support academic research the =
data are openly available to all.

regards,
Chad
