sky command

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

Function:

Sky drives the camera in the same ways as the run command (q.v.) but marks the observation's file as a background frame which improves the handling of the data. Multsky does a sequence of sky observations.

Usage:

   sky [<camera>] <exposure-time> ["<title>"]

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

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