HELP SECTION

CELLSIZE
Type:  Adverb (real array, 2 elements)
Use:   Separation between pixels of a 2-dimensional image.
       The first element is the increment between columns (X)
       and the second element is the increment between rows (Y).
Null Value: 0
       Null value assignment varies with verb or task.

Verbs:
   OBITIMAG......Access to OBIT task Imager without self-cal or peeling.
   OBITMAP.......Simplified access to OBIT task Imager.
   OBITPEEL......Access to OBIT task Imager with self-cal and peeling.
   OBITSCAL......Access to OBIT task Imager with self-cal, NOT peeling.
Procedures:
   CXIMAGR.......Grid UV data into a complex image, Fourier transform,
                 Clean.
   CXPOLN........Procedure to make complex polarization images and beam.
   LINIMAGE......Build image cube from multi-IF data set.
   MAPPR.........Simplified access to IMAGR.
Tasks:
   BOXES.........Adds Clean boxes to BOXFILE around sources from a list.
   BSGEO.........Beam-switched Az-El image to RA-Dec image translation.
   BSGRD.........Task to image beam-switched single-dish data.
   BSMAP.........Images weak sources with closure phases.
   CANDY.........User-definable (paraform) task to create an AIPS image.
   CC2IM.........Make model image from a CC file.
   CHKFC.........Makes images of Clean boxes from Boxfile.
   EVAUV.........Subtracts & divides a model into UV data, does statistics
                 on results.
   FACES.........Makes images of catalog sources for initial calibration.
   FIXBX.........Converts a BOXFILE to another for input to IMAGR.
   IMAGR.........Wide-field and/or wide-frequency Cleaning / imaging task.
   MANDL.........Creates an image of a subset of the Mandlebrot Set.
   MAPBM.........Map VLA beam polarization.
   MODAB.........Makes simple absorption/emission spectral-line image in
                 I/V.
   MODIM.........Adds images of model objects to image cubes in IQU
                 polarization.
   MODSP.........Adds images of model objects to image cubes in I/V
                 polarization.
   MODVF.........Task to create a warped velocity field.
   MOMNT.........Calculates images of moments along x-axis (vel, freq,
                 ch).  CELLSIZE gives width of smoothing function in
                 velocity and in X/Y.
   PATGN.........Task to create a user specified test or primary-beam
                 pattern.
   SCIMG.........Full-featured imaging plus self-calibration loop with
                 editing.
   SCMAP.........Imaging plus self-calibration loop with editing.
   SDGRD.........Task to select and image random-position single-dish
                 data.
   SDIMG.........Task to select and image random-position single-dish
                 data.
   SETFC.........Makes a BOXFILE for input to IMAGR.
   UFLAG.........Plots and edits data using a uv-plane grid and the TV.
                 CELLSIZE must be as used in IMAGR.
   UVMAP.........Makes images from calibrated UV data.
