Dear Firdaus,
SAC does not specify or require the units of the data read in
or written out. The units are digital samples, and the domain
is velocity, acceleration, displacement, pressure, or whatever
the sensor measures. If you carried out "transfer" in SAC
then the domain might have changed, e.g. from velocity to
displacement, but if you did not, then the domain is still
that of the sensor. The manufacturer's data sheet for a
good seismometer will tell you which domain it is in - look
for the units in which the gain is specified e.g. V/(m/s)
for a velocity seismometer or V/(m/s^2) for an accelerometer.

dear all,
i've extracted sac file into text file which contains a time series of particular earthquake. I'm going to import it to EERA in order to have response spectra.
However, i'm little bit confused with physical unit of this time series where it does not mention obviously in this text file.
I've tried to write a command as follow:
%saclst idep f II.COCO.00.BH1.M.2004.361.010030.SAC
the output is
"12345"
i have no idea to solve it.
Kindly advice
regards
