### HELP SECTION

SMODEL
Type: Adverb (REAL(7))
Use: This model specifies a point source model to use, usually instead
of a Clean components model. A non-zero flux density means this
model is to be used if appropriate. The elements of SMODEL are
SMODEL(1) = flux density (Jy)
SMODEL(2) = X offset in sky (arcsec)
SMODEL(3) = Y offset in sky (arcsec)
SMODEL(4) = Model type:
0 => point model
1 => elliptical Gaussian and
SMODEL(5) = major axis size (arcsec)
SMODEL(6) = minor axis size (arcsec)
SMODEL(7) = P. A. of major axis (degrees)
2 => uniform sphere and
SMODEL(5) = radius (arcsec)
3 => uniform sphere and
SMODEL(5) = radius (arcsec)
Null Value: 0
A null value of SMODEL(1) means no model is specified;
the useage of null values for other parameters depend on
the application.
