As of Sun May 22 23:04:57 2022
Type: Adverb (Real array, 64 elements)
Use: Specifies a change or shift of the Right Ascension (or X)
coordinate of an image, one per FIELD. Specifies a shift
Eastward (smaller X-pixel value) of the map center.
The actual new center Right Ascension is given by
RA = RA_0 + RASHIFT(i) / cos (Dec_0)
where Dec_0 is the declination of the reference point.
If more than 64 fields are needed use BOXFILE to specify the
shifts or field centers. RASHIFT is used only if BOXFILE is not.
Null Value: NONE ( 0 => no shift )
BOXES.......Adds Clean boxes to BOXFILE around sources from a list.
CHKFC.......Makes images of Clean boxes from Boxfile.
FIXBX.......Converts a BOXFILE to another for input to IMAGR.
IMAGR.......Wide-field and/or wide-frequency Cleaning / imaging
SCIMG.......Full-featured imaging plus self-calibration loop with
UVCON.... Generate sample UV coverage given a user defined array
CXPOLN......Procedure to make complex polarization images and beam.
LINIMAGE....Build image cube from multi-IF data set.
