Figure 4: Flux-correction factor as a function of off-axis angle
for three different azimuthal angles: (a)
=0 degrees, (b)
= 22.5 degrees, and (c)
= 45 degrees. The pixel numbers
correspond to those in the upper left panel in Figure 3, where the source pixel
is typically pixel 1, pixel 0 is the central pixel, and pixels 2 and 3 are
generally farthest from the source position.
