CASA CARTA Data Analysis

CARTA needs to furnish basic connections to CASA to be used for analytics. The baseline case is to connect to the CASA image analysis package. It seems like the easiest case is to base this around a selection of a region for a file that is available on disk (staying firmly in the CASA paradigm of everything-on-disk).

Case 1: Image statistics on an entire image

Given a small GUI element that selects components in the ia package (here, the tool imstat), pressing the Go button runs the CASA task imstat and returns the output to a window in the GUI or to a terminal running the casapy environment. The latter is probably the most useful, since this allows the parameters of the imstat command to be set in the casapy environment rather than having to use CARTA to wrap the data.

Here's a sample GUI installation using the less-ideal case of text return into CARTA:

Case 2: Image statistics on an ROI

Same as above except a user selects a region of interest in the CARTA viewer that defines a region and passes that region into CASA's imstat command.
