Output

There is a single output file for each session unless a deliberate change is made by the user using the OUTPUT command. This contains the following information:

The name or position of the target and the assumed configuration details.

The J2000 positions of all of the guide stars meeting the selection criteria, up to the specified number.

The calculated guide probe coordinates for each of the guide stars (x y or r ).

The magnitudes of the guide stars (to be used in evaluating integration times).

An asterisk after the probe position indicates that the object is classified as stellar on all GSC plates and a ? represents an ambiguous classification. No symbol is given for objects classified as non-stellar on all plates. These should only be used as guide stars in case of dire need.
