Time-to-depth conversion of SRF

[Wufaxing]

ls the Time-to-depth conversion of SRF available now?

Is there any errors in the S-wave time-to-depth conversion? Theoretically, Both Ps and Sp phases have the same procedure on this function.

yes, I use LQT to calculate SRFs, when I run rf2depth ccp.cfg, it only search files with comp of R

Thanks for reporting this. I'm in holiday now, I'll debug this after back to work at January.

I'm developing S receiver function ccp stacking via seispy during this time and may know this one.

This is partially due to class RFStation and it's api. It needs a sample trace to init RFStation and collect neccessary information like stla, stlo .etc.
Unfortunately, rf2depth didn't leave space for different comp. So by default, seispy is searching xxx_Rxxx.sac file rather than xxx_Lxxx.sac.

It's a little bit awkward time point, since I am working on ccp moduel right now to add S receiver function support and it requires weeks to write, run and go through a set of test.

Here's a couple of suggestions:

1. Take a deeper look into rf2depth function
2. write a py script to do rf2depth rather than rf2depth in commnad.

Hi all
In current version, I have written an API for read L component in RFStation as below

RFStation('path/to/SRF', prime_comp='L')

But this function hasn't been embedded into rf2depth. In the future, the 'rf2depth' will search components order by R, Q, L and Z.
