fflat command

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

Function:

Fflat drives the camera in a simlar way to the  run  command, but performs a full field flat on the detector. The observation file is marked as a full field flat. Multfflat does a sequence of fflat observations.

Usage:

   fflat [<camera>] <exposuretime> ["<title>"]
   multfflat [<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 multfflat. The title-string must be enclosed in double quotes.

Notes and caveats

  1. This command is only available for the WEAVE science cameras.
