Thread: Does Mustang work?

Hi Shahar,

It's great to see that you're giving MUSTANG a try! Let me see if I can
shed some light on why the query you sent isn't working… Here is a similar
query that does work:

http://service.iris.edu/mustang/measurements/1/query?metric=orientation_check&net=XD&sta=A01&cha=BH[12ENZ]&format=text&timewindow=2011-09-30T21:32:19,2015-10-05T21:32:19

I made 5 changes to your original query:

1) changed http://service.iris.edu/mustang/metrics to http://service.iris.edu/mustang/measurements
2) deleted &loc=--
3) I used BH[12ENZ] instead of BH*
4) changed &output=html to &output=text
5) changed the year of the end date to 2015

Explanations
-----------------
1) we try to use "metric" to mean the algorithm that's running and "measurement" to mean the values
computed by the algorithm that get stored in the database. (In a week, a channel will have 7 measurements
for a single metric.) So unless you want information about the algorithm itself, you'll want to choose the
_measurement_ service (not _metrics_).

2 & 3) The MUSTANG measurement service doesn't yet use the same wildcarding as the other web
services, or even the noise-pdf, noise-psd services. We hope to fix that. The wildcards above should
get you the measurements you are looking for.

4) I find I get the most useful output if I use output={text, xml or csv}. I'm not sure why HTML wasn't designed
to return similar output…

5) orientation_check only runs when there's an M>=7 event that is shallower that 100 km. The station was
running from 2011/01/14-2012/08/18 and I'm seeing measurements only for 2012/02/02 through 2012/04/11.
I tried your original timespan for the IU network and it looks like there weren't any suitable events during
that week.

Please let me know if you have any additional questions.

Best regards,
Mary Templeton

Hi,

I tried using mustang, but it doesn't work. I tried with various networks/station combinations, and also tried to change other parameters such as channel, etc.
I always get a "400 No targets were found after filtering"

For example"
http://service.iris.edu/mustang/metrics/1/query?metric=orientation_check&net=XD&sta=A01&loc=--&cha=BH*&output=html&timewindow=2011-09-30T21:32:19,2011-10-05T21:32:19
