Visual 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.
Preview all good PRFs
ctrl+s or cmd+s
Re-calculation of RFs#
As a final-list saved into RF output path, events information of RFs can be invoked for re-calculation if we need to change some parameters, such as gauss factor, bandwidth of filter or deconvolution method. After version 1.2.14, the
prf command introduce a new option of
-f for re-calculation using events in the final-list.
