write script to compare DEGAS data with EMPIRE data

[aakepley]

Purpose: check on the correctness of our calibration. The idea here is that we are calling DR1 "good enough" when the DEGAS pixel values are within 20% of the EMPIRE pixel values for the same galaxy.

Input: DEGAS Cube
Output: plot comparing EMPIRE vs. DEGAS pixel values.

Pieces that need to be built:

• Function to find EMPIRE data corresponding to input DEGAS cube (assume EMPIRE data on local disk)
• Function to smooth DEGAS data to EMPIRE spatial resolution (preserving the units)
• Function to regrid the DEGAS data to EMPIRE pixel scale
• Function to regrid the DEGAS data channels to the EMPIRE channels (Maybe able to be combined with above)
• Function to output the plot

Note that this functionality is language/feature agnostic -- it could be written in whatever language/program people find easiest (CASA, python, idl).

The second part of the task is to actually use this script to generate the plots and examine them.

Jen and Maria put together an initial version of this script, but we need to get the DEGAS data in a state where it will be useful to run it.
