# <synopsis>

# imcontsub_test.py is a Python script that tests the correctness

# of the imcontsub task in CASA.

#

# The tests include:

#    1. Incorrect input for each paramter.  Incorrect input includes

#       one input of the incorrect data type, out-of-bounds (where

#       applicable, and correct data type but non-sensical.

#    2. A set of sample continuum subtractions with expected

#       output

#    3. Calculating one example for each allowed fitorder

#    4. Continuum subtraction with region selection on the sky,

#       channels, and stokes values, as well as using an input

#       region file.

#

# In the imcontsub task a specified continuum channel is subtracted

# from spectral line data.

#

# The expected input is a spectral line image. Both a continuum

# image and a continuum-subtracted spectral line are created as
