Name: fpBIN-rrrrrr-bc-ffff.fit, where rrrrrr is the imaging run number, b is the filter used (u, g, r, i, or z), c is the column location in the Imaging Array of the CCD which acquired the data (1-6), and ffff is the field number within the run.

fpC and fpBIN
header keyword SKY), scaled up a factor of
BINFAC (== 2^SHIFTED), with
SOFTBIAS added afterwards. All pixels that are in atlas
images are replaced by the background level before binning and sky
subtraction, with suitable noise added. All of the header parameters
from the raw image are inherited as well.
