BAIT: pointerr procedure

NAME

pointerr - determines telescope pointing errors

SYNOPSIS

pointerr

DESCRIPTION

pointerr positions the telescope to the RA, DEC, and EPOCH specified in the environment, sets the filter to the value of $FILTER and takes an exposure of time $EXPTIME. It then locates the brightest star in the field and determines its offset from the center of the field. The result is concatenated to the file $REQID.log.

The file format is of the form:

ha dec ha_diff dec_diff ha_err dec_err $OBJECT

Where ha_diff and dec_diff are the observed-predicted positions and ha_err and dec_err are the pointing errors calculated by the telescope. All angles are in decimal degrees.

The program will fail if the file pointerr.abort is present in the current data directory.
