Summary

Algorithm to sort detectors by distance.

Properties

Name Direction Type Default Description
Workspace Input Workspace Mandatory Input workspace
UpstreamSpectra Output int list    
UpstreamDetectorDistances Output dbl list    
DownstreamSpectra Output int list    
DownstreamDetectorDistances Output dbl list    

Description

Algorithm to sort detectors by distance. Will return arrays for upstream (downstrem) spectrum number and detector distances, ordered by distance.

Usage

# create some workspace with an instrument
ws = CreateSampleWorkspace()

upIDs,upDistances,downIDs,downDistances=SortDetectors(ws)

# No upstream detectors
print "Type of upID:",type(upIDs)
print "Number of upDistances:",upDistances.shape[0]
#Downstream detectors
print "First few values of downIDs: ", downIDs[0:5]
print "First few values of downDistances: ", downDistances[0], downDistances[1], downDistances[2], downDistances[3],downDistances[4]

Output:

Type of upID: <type 'numpy.ndarray'>
Number of upDistances: 0
First few values of downIDs:  [ 0  1 10 11  2]
First few values of downDistances:  5.0 5.0000064 5.0000064 5.00001279998 5.00002559993
