Hello,
I am trying to remove instrument correction from seismogram (downloaded through Wilber) using TRANSFER command. But, I am not able to figure out the units. In SAC file the units are given in displacement by default, but the response file units are generally reported in velocity units.
How the transfer command handle these units in FROM & TO options?
Thank you.

Hi,
I want to down-sample my data from 100 samples/second to 40
samples/second. As per the SAC manual, decimate function has only integral
factor (from 2 to 7) to down-sample the data. Is there any possible way to
use decimate function or any other function to down-sample from 100 to 40
samples/second. I would be grateful for any suggestion in this regard.
Thanks
Abhash Kumar

Hi,
I have several SAC files and I want to output the value of a particular
header variable of each SAC file to a text file. Is it possible (or any SAC
command) to print out the value of a header variable in the SAC terminal
and save it to a text file. I would be grateful for any suggestion in this
regard.
Best regards
Abhash Kumar
