instrument response of all of them.
1) Some of the events have the components called BH1 and BH2 (or BH2 and
BH3) instead of BHE and BHN. To rotate, I need to know which one is BHE and
which one BHN. For that, I watched the header information looking for
CMPAZ=90 - CMPINC=90 for East component BHE, and CMPAZ=0 - CMPINC=90 for
North component BHN.
The problem was that in some cases the numbers of the CMPAZ were not the…
