HELP SECTION

NMAPS
Type: Adverb (REAL)
Use:  Specifies the number of maps used in the operation.  Often it is
      the number of facets used for the source model.
Null value:  None
Verbs:
   AVMAP.........Advance tape by one image (IBM-CV = obsolete tape file).
Procedures:
   OOCAL.........Determines antenna complex gain with frequency-dependent
                 models.
   OOFRING.......Fringe fit data to determine calibration with spectral
                 index options.
   VLBABPSS......Computes spectral bandpass correction table.
Tasks:
   BLCAL.........Compute closure offset corrections.
   BLCHN.........Compute closure offset corrections on a
                 channel-by-channel basis.
   BLING.........Find residual rate and delay on individual baselines.
   BPASS.........Computes spectral bandpass correction table.
   CALIB.........Determines antenna calibration: complex gain.
   CAPLT.........Plots closure amplitude and model from CC file.
   CLPLT.........Plots closure phase and model from CC file.
   CPASS.........Computes polynomial spectral bandpass correction table.
   EVAUV.........Subtracts & divides a model into UV data, does statistics
                 on results.
   FIXBX.........Converts a BOXFILE to another for input to IMAGR.
                 NMAPS is the old number of facets.
   FLATN.........Re-grid multiple fields into one image incl sensitivity.
                 NMAPS is the number of pointings.
   FRING.........Fringe fit data to determine antenna calibration, delay,
                 rate.
   IBLED.........Interactive BaseLine based visibility EDitor.
   IMLOD.........Reads tape or disk files to load images to disk.  NMAPS
                 refers to advancing over a very old format of images.
   KRING.........Fringe fit data to determine antenna calibration, delay,
                 rate.
   LPCAL.........Determines instrumental polarization for UV data.
   LTESS.........Makes mosaic images by linear combination.
   MOD3D.........Computes a 3D CC model from a set of facets.
   OOSUB.........Subtracts/divides a model from/into a uv data base.
   PCAL..........Determines instrumental polarization for UV data.
   RLCAL.........Determines instrumental right-left phase versus time (a
                 self-cal).
   SCIMG.........Full-featured imaging plus self-calibration loop with
                 editing.  NMAPS is the number of self-cal loops.
   SCMAP.........Imaging plus self-calibration loop with editing.  NMAPS
                 is the number of self-cal loops.
   STESS.........Task which finds sensitivity in mosaicing.
   UTESS.........Deconvolves images by maximizing emptiness.
   UVADC.........Fourier transforms and corrects a model and adds to uv
                 data.
   UVCON.........Generate sample UV coverage given a user defined array
                 layout.
   UVMAP.........Makes images from calibrated UV data.  NMAPS is the
                 number of frequency channels to image.
   UVSUB.........Subtracts/divides a model from/into a uv data base.
