how to prepare offline station data for rf study about seispy

[xumi1993]

The raw data should be cut including P arrival, such as

• From 100 to 1000s relative to origin time. The 100 needs to be set to offset in configure file.
• From -100 to 200s around theoretical P arrival. In this case, the omarker and kztime should be the origin time, b should be the relative time length referring to omarker, and the offset is set to empty in configure file

Note that the stla, stlo and stel in sac header are also required for prf scheme.

How can it be done, can you please provide supportive codes. I don't find any relevents codes in your package.

Sorry, it isn't a part of Seispy.

As a new user to receiver functions, It would be better if you can provide/suggest ready made code doing this. I have only raw data recorded in a station saved in a directory. How can i compute rf using the same data sets. I have only stla,stlo,elevation information.

Cutting out event records from raw data is a basic skill for seismic data processing. The raw data also have different formats in Reftek, mseed, segy and SAC. The arrangement of these data is also different when they were extracted from data loggers. So it's difficult to develop a unified method to prepare the data.

So seispy cannot be implemented for any offline stations, right?

[xumi1993]

You can cut out event data first and then use Seispy for RF calculation.

ok sir, as i am new to this field i donot know how to cut the data wrt P onset time. I already converted 1 hr data files to the sac format.Does it require to merge whole data sets.Moreover if you can suggest some links it would be helpful.
