Description#
Extract the values for momentum transfer stored in the vertical axis of a MatrixWorkspace representing the dynamic factor \(S(Q,E)\), or compute the values of a MatrixWorkspace representing the dynamic factor \(S(\theta,E)\).
Usage#
** Extract Q values from \(S(Q,E)\) workspace **
workspace = LoadDaveGrp("BASIS_59689_divided.dat")
qvalues = GetQsInQENSData(workspace)
# print the first three values
vals = ' '.join(['{0:6.3f}'.format(Q) for Q in qvalues[0:3]])
print("'{}'".format(vals))
' 0.300 0.500 0.700'
workspace = LoadNexus("osiris97944_graphite002_red")
qvalues = GetQsInQENSData(workspace)
# print the first three values
vals = ' '.join(['{0:6.3f}'.format(Q) for Q in qvalues[0:3]])
print("'{}'".format(vals))
' 0.189 0.244 0.298'
