Dear Sac Users,

I'm PhD student from Morocco , i work on the attenuation of wave seismic .
Is there any macro or script to determine the quality factor Qc using
SAC software ?


Thank you in advance for your reply.

    Hello Abderrahim, 

    Qc generally refers to scattering attenuation and if you want to calculate that, you may look at the following paper:


    Leyton, F., and K. D. Koper (2007), Using PKiKP coda to determine inner core structure: 2. Determination of QC,
    J. Geophys. Res., 112, B05317, doi:10.1029/2006JB004370

    On the other hand, if you are referring to Q in general, then you may have to use a synthetic seismogram algorithm like reflectivity. 

    Januka.
