Functionality

The LSF results from the convolution of several physical components starting from the angular distribution of light incident on the gratings from the mirrors given in XRT1_XPSF and XRT2_XPSF. The specific RGA components described here are

FIGURE
Misalignment distribution of the set of elements in the grating assembly.
BOWS
Non-flatness distribution of the set of elements in the grating assembly.
SCATTER
Small-angle scatter from grating surface.
LASCAT
Large-angle scatter from grating surface.
