rdseed problem with header information
2017-02-07 07:24:04
Hello,
I have to convert my antelope database into sac files. I have been using db2sac without problem, but I am not sure db2sac can handle polarity reversal ( I have a bunch of L22 sensors for which I will have to correct for polarity). Since I couldn’t find anywhere if db2sac support this conversion, I have been trying to use rdseed v5.3.1. In order to populate the header I am using my dataless in this fashion: rdseed -d -o 1 -z 1 -f myday_volumes(miniseed) -g mydata.dataless.
I can convert my day volumes into sac files with no problem, but in the end all the header information like lat/lon/elev or dip/azimuth delta etc is are gone.
Any help will be appreciated. Thank you!

Regards,
Federica Lanza

    Hi Federica-

    If you have rdseed also output the SAC Poles and Zeroes file, can you use that as your source of station location input in SAC?
