The PSD_spinDmon McStas Component

Position-sensitive monitor, measuring the spin-down component of the neutron beam.

An (n times m) pixel PSD monitor, measuring the spin-down component of the neutron beam.

Example: PSD_monitor(xmin=-0.1, xmax=0.1, ymin=-0.1, ymax=0.1, nx=90, ny=90, ﬁlename="Output.psd")

Parameters in boldface are required; the others are optional.
