Virtual check PRFs with an user interface¶
Open the user interface¶
Following previous steps, PRFs have been calculated and save to SAC files in a folder named as the station name.
net.sta ├── 2018.229.15.35.02_P_R.sac ├── 2018.229.15.35.02_P_T.sac ├── 2018.229.22.06.55_P_R.sac ├── 2018.229.22.06.55_P_T.sac │......
For example, PRFs were saved in folder
net.sta. the file name of the PRF must be in
%Y.%j.%H.%M.%S_P_[RT].sac. Now input following command to open the UI to browse the PRFs and reject poor PRFs.
$ pickrf /path/to/net.sta
The window will open as following image. Each page will display 20 PRFs. You can press
c hotkey or click
next button for turning pages.
Directly click PRFs on the interface to set up them to ‘poor’ PRFs. The PRFs will turn gray when you click a PRF. If you click again, it will restored to a ‘good’ PRF.
When you have selected all PRFs, please click
finish button to delete all ‘poor’ PRFs. Then a list file named as
net.stafinallist.dat will be generated automatically in the folder, which include following columns
Event name: the event name with format as
Phase: the phase name (same as that in file name).
Epicenter distance in degree
Ray-parameters in s/km
This list file is very important for derived method such as H-k stacking and CCP stacking.
enlarge and reduce visual amplitudes of the waveforms¶
Amp enlarge and
Amp reduce are available to control the visual amplitudes.
Preview all PRFs¶
space hotkey and
preview button provide a function to plot all ‘good’ PRFs. Use
ctrl+s on Linux/Windows and
cmd+s on MacOS to save this figure as a PDF file.
