7# the solution here to findCalModels should be reworked

8# CASA5 uses the casa dict to set the default roots parameter values

9# and that dict is not available in CASA6, where ctsys.resolve is

10# available

11# Here: defaultRoots is defined differently for CASA6 and CASA5 and

12# that values is used as the default value for the roots parameter in

13# findCalModels.

14# Inside findCalModels there is a new section at the top to use

15# ctsys.resolve to make the initial attempt to find the models.

16# If that fails or is unavailable it falls back to the CASA5 code.
