### TRACK

The TRACK observing mode simply tracks one position relative to the source. It is normally used with FREQUENCY SWITCHING and offsets in /SYSTEM projection.

The basic parameters are the offsets for the position to track; parameters of the options are the (total) number of subscans, and the time per subscan in [s].

After you enter a track setup manually, we recommend to “save” it, optionally to a named file:

SAVE TRACK [/FILE track-1]

It can then at any later time be reloaded with @ track[-1], see HELP SAVE.

You may want to save the switching mode seperately or with TRACK into the same file:

    SAVE SWITCHING /FILE track-2
    SAVE TRACK     /FILE track-2 /APPEND
