flat command

This page is from the ING manual INS-DAS-29 Operations manual for UltraDAS.

Function:

Flat drives the camera in the same ways as the run command (q.v.) but marks the observation's file as a flat field which improves the handling of the data. Multflat does a sequence of flat observations.

Usage:

   flat [<camera>] <exposuretime> ["<title>"]

   multflat [<camera>] <n-obs> <exposure-time> ["<title>"]

where exposure-time is the exposure time for one cycle in seconds and n-obs is the number of cycles in multflat. The title-string must be enclosed in double quotes. The default title is "Flat Field".
