Dear members, I am trying to use IRIS DMC data from "Bhuj aftershock study" network. ( My attempts with removing instrument response produced unrealistic amplitudes for all the three components. I followed these steps: Downloaded mseed and dataless files Extracted the SAC formated data and response files using rdseed In SAC, read the data and removed the instrument response using following steps, * rmean * rtrend * taper * transfer from evalre… [more]

Hai all, sorry to bother but I need your help about how to picking traveltime in PRS result? I already plot my green's function from cross correlation (I'm doing ambient noise analysis) as a multi green's function (using prs) and hoping can get a velocity reference from plotting between distance vs traveltime. I just don't know how to picking it, is there any step for it?? Thank you.

Hello to all! I’m having some trouble regarding the Amplitude. I need to print the amplitude in HYPO pick file; I have to get the first arrival amplitude just for earthquaque location with one station. Hoping to hear from you soon, have a great day Cheers
