When trying to remove the instrument response using evalresp
(sac-command: transfer from evalresp fname RESP.AU.ARMA..BHZ to vel
freqlimits 0.005882 0.006250 0.250000 0.333333) we get the following error:
EVRESP ERROR (ARMA.AU..BHZ [File: ./RESP.AU.ARMA..BHZ; Start date:
2006,340,00:00:00.0000; Stage: 5]):
parse_coeff; Unsupported filter type, IIR and Analog filters
should be represented as blockette [53] filters,
skipping to next response now
No transfer function applied!
ERROR 2118: No transfer function applied.
We found a work-around in the sac-mailing list
(http://www.iris.washington.edu/pipermail/sac-help/2006-October/000160.html)
but we neither understood the problem nor did we find a satisfying
solution. Did anyone else encounter that problem? We'd be grateful for
any support in this matter.
Thanks!
