Description¶
Algorithm to mask detectors in particular banks, tube, or pixels.
To use the Bank argument, the instrument must be one of: ARCS, BIOSANS, CG2, CNCS, CORELLI, D33, EQ-SANS, HYSPEC, MANDI, NOMAD, POWGEN, SEQUOIA, SNAP, SXD, TOPAZ, WAND, WISH.
For instruments with rectangular position sensitive detectors (POWGEN, SNAP, TOPAZ), the tube is corresponding to the x coordinate, and pixel to the y coordinate.
For example, on SNAP Bank="1", Tube="3" corresponds to SNAP/East/Column1/bank1/bank1(x=3), and Bank="1", Tube="3", Pixel="5" is SNAP/East/Column1/bank1/bank1(x=3)/bank1(3,5).
If one of Bank, Tube, Pixel entries is left blank, it will apply to all
elements of that type. For example:
MaskBTP(w,Bank = "1")will completely mask all tubes and pixels in bank 1.MaskBTP(w,Pixel = "1,2")will mask all pixels 1 and 2, in all tubes, in all banks.
The algorithm allows ranged inputs:
Pixel="1-8,121-128"is equivalent toPixel="1,2,3,4,5,6,7,8,121,122,123,124,125,126,127,128"
Alternatively, the Components argument can be used to select named components instead of Banks.
This is can be used for masking entire sub-components of an instrument.
Note
Either the input workspace or the instrument must be set. If the workspace is set, the instrument is ignored.
Usage¶
a=MaskBTP(Instrument='CNCS',Tube='1-3')
b=MaskBTP(Workspace='CNCSMaskBTP',Instrument='CNCS',Bank='40-50',Pixel='1-10')
c=MaskBTP(Workspace='CNCSMaskBTP',Instrument='CNCS',Bank='42')
print("Detectors masked")
print("Step 1: 50 * 3 * 128 = {0.size}".format(a))
print("Step 2: 11 * 8 * 10 = {0.size}".format(b))
print("Step 3: 1 * 8 * 128 = {0.size}".format(c))
print("Here are some of the masked detectors:")
instrument=mtd['CNCSMaskBTP'].getInstrument()
print("A pixel Bank 42, detector 42700: {}".format(instrument.getDetector(42700).isMasked()))
print("Pixel 1 in Tube 4 in Bank 45, detector 45440: {}".format(instrument.getDetector(45440).isMasked()))
print("Pixel 100 in Tube 2 in Bank 45, detector 45283: {}".format(instrument.getDetector(45283).isMasked()))
print("")
print("And one that should not be masked")
print("Pixel 128 in Tube 8 in Bank 50, detector 51199: {}".format(instrument.getDetector(51199).isMasked()))
Output:
Detectors masked
Step 1: 50 * 3 * 128 = 19200
Step 2: 11 * 8 * 10 = 880
Step 3: 1 * 8 * 128 = 1024
Here are some of the masked detectors:
A pixel Bank 42, detector 42700: True
Pixel 1 in Tube 4 in Bank 45, detector 45440: True
Pixel 100 in Tube 2 in Bank 45, detector 45283: True
And one that should not be masked
Pixel 128 in Tube 8 in Bank 50, detector 51199: False
