unknown physical units ...
2013-02-15 06:15:33
Dear SAC users,

I downloaded some SAC data files using the JWEED program. What I wondered why the IDEP variable shows unknown physical units (displacement, velocity, volts, etc). The seismograms looks pretty good except that their physical units are unkown (IDEP = 5; 5 = UNKNOWN).
How can figure out their physical units ? Are the data corrupted or wrong retrieved ?

I appreciate some suggestion please

    I think seismogram download from Jweed is IDEP header is (VEL) Velocity and
    not corrupted data.
