SetDetScale dialog.¶
Summary¶
Set/change the detScale parameters for a MatrixWorkspace or PeaksWorkspace instrument

MatrixWorkspace or PeaksWorkspace with instrument. |

DetScaleList |
Input |
str list |
Comma separated list detectorNumbers:detScales eg. 13:1.046504,14:1.259293 |
|
DetScaleFile |
Input |
string |
Optional text file with detector number and its scale on each line separated by spaces. Allowed values: [‘txt’] |
Description¶
Given a PeaksWorkspace or MatrixWorkspace with an instrument, this algorithm will set or change the detector bank scales that are used in SaveHKL and AnvredCorrection. The input format is the same as used in anvred3.py, so DetScaleList input can be pasted from the definition of detScale there. Alternately, there is an option, DetScaleFile, to read a text file with each line containing the detector number and scale factor for that detector. If scales for a detector are given in both the DetScaleList text string and DetScaleFile, the values from the text string will be used. The default values can be set in the instrument parameter file.
Usage¶
Example:
w=LoadIsawPeaks("TOPAZ_3007.peaks")
print("Before SetDetScale:")
print('{0:.5f}'.format(w.getInstrument().getNumberParameter("detScale17")[0]))
print('{0:.5f}'.format(w.getInstrument().getNumberParameter("detScale49")[0]))
#This SetDetScale will change the parameters set in parameter file
SetDetScale(Workspace=w, DetScaleList='17:1.0,49:2.0')
print("After SetDetScale:")
print('{0:.5f}'.format(w.getInstrument().getNumberParameter("detScale17")[0]))
print('{0:.5f}'.format(w.getInstrument().getNumberParameter("detScale49")[0]))
Output:
Before SetDetScale:
1.18898
0.79420
After SetDetScale:
1.00000
2.00000
