Hello All,
I used following command to remove instrument response
sac << END
r ${fname}
rmean
rtrend
taper w 0.01
transfer from polezero s $response to none freq 0.008 0.016 1.0 2.0
write ${fname}_noresp
q
END
And i got the following error ,
polezero-comment: Error parsing datetime: ' CREATED : 2019-09-05T18:41:21.767459Z'
polezero-comment: Error parsing datetime: ' START : 2010-08-03T17:00:00.000000Z'
polezero-comment: Error parsing datetime: ' END : 3000-01-01T00:00:00.000000Z'
Using polezero response for WSS, BHN, CI, ...
Station (WSS ), Channel (BHN )
station is WTT2

Does anyone know why this is happening ? It doesn't give an error for all the stations in my file. only for few stations I get this error .

Dear Rashni -
SAC is telling you that it doesn’t recognize the time/date format and is being helpful telling you specifically which entry is invalid. Based on my knowledge of SAC’s time formats, they shouldn’t end with Z — so, your response file seems to have an incorrect format. (I also doubt that SAC can do anything sensible with microsecond-level time resolution but that’s not necessarily a format error.)
SAC is lazy about reading a pole-zero response file: it only reads as much as it needs to find something relevant for a particular station/component/network/locid combination. If the improperly formatted lines appear later than the correct one for a station, it won’t complain. That explains the intermittency of the complaints about a bad format.
