Description


Cylindrical monitor on the x-z plane outputting a series of energy-planes in a subset of reciprocal 
space, spanned by scattering vectors qa(x,z) and qb(x,z).

The radius and yheight parameters are not used for propagation, but only to define the outgoing divergence 
limit considered when estimating k_f

The assumption is that the "current" neutron represents the final state, whereas the incoming state
is found by restoring the neutron state "index" components earlier.

Example: Sqq_w_monitor(filename="output",radius=1, yheight=0.05, Emin=0,Emax=5,nE=11,nqa=100,nqb=100,qamin=1,qamax=10,qbmin=1qbmax=10,index=-2)
         AT (0,0,0) RELATIVE sample
