How can I compute the flux in a region for all images in an image cube FITS file?
In the GUI, use the Window_Control / Multi-Panel Options button, select the panels you’re interested in, and click ‘Compute Image Flux’. Note: To define a region manually (by drawing it), first display a single panel, from the Main GUI window, click Plot_Control / Image Flux, draw the region, and click Accept to exit the image flux widget. Then select multiple panels, click ‘Compute Image Flux’ and select ‘Used Stored Boxes’. To define the region by contour level, this extra step isn’t necessary. One of the options in the image flux widget is to write (or append to) an output text file.
