Remove the prompt pulse tor a time of flight measurement
#Create a workspace
from numpy import *
x=arange(0,100000,10)
y=0*x+1
w=CreateWorkspace(x,y[1:],UnitX="TOF")
#apply algorithm
w1=RemovePromptPulse(w,Width=5000,Frequency=50)
#The prompt pulses at 50Hz are at 0, 2e4, 4e4, 6e4,8e4 microseconds
#do some checks
x=w1.dataX(0)
y=w1.dataY(0)
print("Y( {} ) = {:.1f}".format(x[100], y[100]))
print("Y( {} ) = {:.1f}".format(x[1000], y[1000]))
print("Y( {} ) = {:.1f}".format(x[4100], y[4100]))
print("Y( {} ) = {:.1f}".format(x[5000], y[5000]))
Output:
Y( 1000.0 ) = 0.0
Y( 10000.0 ) = 1.0
Y( 41000.0 ) = 0.0
Y( 50000.0 ) = 1.0
The spectra should look like
