This is the value of SAMPOFF from the Support Schedule. SAMPOFF is the
offset of the image in photocathode pixel coordinates in the sample (X)
direction from the beginning of the photocathode. For a 1024 by 1024
image, a photocathode sample value of 1 corresponds to image X value
of 1024, and vice versa.
