Feature request - flux density and other stats in Stokes analysis tool #1181

Open Jordatious opened 4 years ago

Jordatious commented 4 years ago

In the Stokes analysis tool in CARTA, the values (e.g. within a region) seem to represent the mean of all the pixels. It would be useful to change this statistic like you can in the spectral profiler. In particular, using the flux density of a region. Currently to do this, I have to export the table for each Stokes vector from the spectral profiler and plot it myself. It could even be cool to “transmit” from the spectral profiler to the Stokes analysis tool.

@arusstaylor would we still calculate PI and PA in the same manner when using flux density instead of mean? presumably the beam size and frequency dependence would just cancel out?
