Question: SDS format CHAN.TYPE - MSNoise - BIRA-IASB Mailing lists

8 Nov 2018

Hi MSNoise folks,

I am trying to run some correlations with data downloaded using ObspyDMT.
After downloading I converted the file structure to the SDS convention
using the dataselect tool. I guess these data have type M set in their
headers because CHAN.TYPE = BHE.M.

I was trying to scan my archive with MSNoise, but nothing was being found.
This was because MSNoise is only looking for data type D. I noticed the
stdout says it was looking for data in, for example,

/Volumes/ESLab/Data_02/POLENET/msnoise_SDS_database/2010/YT/CLRK/*.D,...

when it should have been looking for
/Volumes/ESLab/Data_02/POLENET/msnoise_SDS_database/2010/YT/CLRK/*.M,...
 (or not worrying about type D or M at all)

I figured out that I could simply hardcode my type into the configuration
using
YEAR/NET/STA/CHAN.M/NET.STA.LOC.CHAN.M.YEAR.DAY
but I am curious as to why type D is hardcoded into MSNoise?

P.S. Another small thing I noticed this morning when trying to get things
working.

1) The webpage for scan-archive
<http://msnoise.org/doc/workflow/003_scan_archive.html> is slightly wrong
in the syntax of the command. The webpage says to use the command

$ msnoise scan_archive

but it should be

$ msnoise scan-archive

with a dash, not an underscore. It might be nice to fix that webpage since
that is where most people go for the tutorial.
