Thread: Re: Does Mustang work?

Hi Shahar,

I know people who have done that, although I haven't done it
myself.
We don't have a special script like our irisFetch script for the
dataselect web
service, but I suspect people may just call curl or wget.

I'm forwarding your email back to the Web Services list so that
other
matlab/MUSTANG users can share how they do it.

cheers,
Mary

Hi Mary,

Thank you. Is there a way to call Mustang from within Matlab?

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,

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
