Issue DM-7059: Plot sources/source density on WCS quiver plots
We should show the individual sources (size/color scaled by S/N?) that went into the jointcal fit, and/or a density map of the sources (scaled by S/N?) under the quiver plots. This will help distinguish areas with poorly constrained fits or where the TAN-SIP function diverges, from those where the new WCS really is odd.
