Thread: Stacking seismograms in bins of backazimuth and slowness

Hi,

I want to stack seismograms (receiver-functions) into ray parameter and
back-azimuth bins.

1. Unless you guys recommend otherwise, I think I should use *sumstack *in
the *SSS *subprocess. The *sumstack *command says you can *"turn
normalization option on or off. When this option is on the resulting
summation is normalized by dividing each point by a factor that is the sum
of each file's weight*." Where is this weight stored and how do I change
it? It doesn't say in the documentation (
https://ds.iris.edu/files/sac-manual/commands/sss.com/sss.html), or I've
missed it.
2. Anyone has a script ready (in SAC/bash/python) to do the binning?


Thanks,

Shahar
