Hi Garrett,

    Does isotropicsqw have the ability to focus onto a detector like several of the other components do? I tried the target_x,target_y,target_z parameters and that is not the correct syntax.
I’m running mcstas2.1-5414

The only focusing option available with Isotropic_Sqw (and btw. also PowderN) is the d_phi which limits scattering to an angular band around the scattering plane. - And this only works in a meaningful way if combined with order=1, i.e. with single scattering only.
