For ROSAT HRI data, this task allows computation of the count rate
from a specified source region. The result is corrected for the point
response function (using the accurate, off-axis PRF), vignetting and
quantum efficiency effects. Note that the size of a region cannot be
specified in celestial coordinates (e.g., arcminutes) for this task (1 pixel = 0.5
for the ROSAT HRI).
