HELP SECTION
REFANT
Type: Adverb (scalar)
Use: This adverb specifies the desired reference antenna for
antenna based phase like calibration (e.g. phase, delay
and rate). The reference antenna should be picked with
some care.
Null value:
0 => pick one.
Verbs:
OBITPEEL......Access to OBIT task Imager with self-cal and peeling.
OBITSCAL......Access to OBIT task Imager with self-cal, NOT peeling.
Procedures:
BASFIT........Fits antenna locations from SN-table data.

offsets.
DOOSRO........Calibrating amplitude and phase, and imaging VLA data.
DOVLAMP.......Produces amp calibration file for phased-VLA VLBI data.
IMFRING.......Large image delay fitting with IM2CC and OOFRING.
