Survey multiple nights of acm data files to locate nights that have calibration images like bias or dark frames. As the name implies, this is a faster version of the acm_nights. This codes does not use codes that compile a variety of table files, but rather just uses header information gathered with direct gethead runs to compute numbers of bias, ddark, and open images. The routine that performs the type assignment is fast_imgtypes.
