Context

without restricting q range (unregularized)

  • Started doing some preliminary MGE fitting and background information gathering for N410 while we try to track down the spectra.
  • I've done our usual MGE fitting (unregularized) for a few different bounds on sigma (0,1,2,3,4) pixels from the center:
    • I likely need to go back and regularize these given the distribution of some of the q' values (reaching sometimes ~0.4 or so, severely limit deprojection).
    • The MGEs look alright, but I think there is some work that can be done. There seems to be a lot of contaminating light in the original image (see below), but we already are applying a mask, so unsure what to do beyond that.
