Questions on image analysis
Q1: Is the viewer caching my image?
Q2: How do I create the final 3x3 image overlay in this guide? I tried to do it, but the viewer does not overlay the velocities properly. (The viewer appears to be ignoring the velocities and instead matching channels between cubes. Unfortunately, the CN and CO cubes have start channels that are offset in velocity space.)
Q3: It is possible to display multiple raster images simultaneously in different panels of the viewer. Is it possible to display multiple contour maps in the same way?
Q4: There are two nuclei in this galaxy. How can I overlay their positions on the various contour/colorscale images?
Q5: In immoments for producing mom1, & 2 maps, there is a parameter mask=' Antennae_South.CO3_2Line.Clean.pcal1.image>0.009*3'. This is different than includepix. Why shall we use a mask rather includepix?
