Saves the geometry information of the detectors in a workspace into a PAR format ASCII file. The angular positions and linear sizes of the detectors are calculated using FindDetectorsPar v1 algorithm.
Tobyfit PAR file is an ASCII file consisting of the header and 5 or 6 text columns. Mantid generates 6-column files. Header contains the number of the rows in the phx file excluding the header (number of detectors). The column has the following information about a detector:
Column Number | Column Description |
---|---|
1st | sample-detector distance (secondary flight path) |
2nd | scattering angle (deg) |
3rd | azimuthal angle (deg) (west bank = 0 deg, north bank = -90 deg etc.) Note the reversed sign convention wrt the .phx files. For details, see: SavePHX v1 |
4th | width (m) |
5th | height (m) |
6th | detector ID – this is Mantid specific value, which may not hold similar meaning in files written by different applications. |
You should expect to find column 6 to be the detector ID in Mantid-generated par files only.
Example - Save PAR file
# import os funcions to work with folders
import os
# create sample workspace
ws = CreateSampleWorkspace()
# test file name
file_name = os.path.join(config["defaultsave.directory"], "TestSavePar.par")
# save the file
SavePAR(ws,Filename=file_name);
print("target file exists? {0}".format(os.path.exists(file_name)))
Output:
target file exists? True
