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.

layout.
UVMAP.........Makes images from calibrated UV data. NMAPS is the
number of frequency channels to image.
