run command

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

Function:

Run exposes the camera, reads it out and saves the data in a FITS file. The file is passed to the archiving and logging facilities. The observation is assumed to be a science exposure (c.f. runs made by the dark and bias commands. Multrun makes a series of runs.

A title may be given for the observation: the title appears as the datum of the OBJECT keyword in the FITS headers and as the target name in the observing log. If no title is given, the system attempts to read the target name from the TCS: this makes the value for the OBJECT keyword the same as that for the CAT-NAME keyword. If the TCS does not answer, then the title defaults to "(object not named)".

Usage:

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

   multrun [<camera>] <n-obs> <exposure-time>

where exp-time is in seconds and n-obs is the number of cycles in a multrun. The title-string must be enclosed in double quotes.

Notes and caveats:

In general, run and multrun should not be used for the specialized type of observations covered by arc, bias, flat and sky. The latter commands set the OBJTYPE and IMAGETYP values correctly in the header such that arcs, flats etc are easy to find in the observation archives.
