MGE Plot

• Here's an attempt at a new MGE figure, this time with both the deprojected 3D density and the 2D surface brightness with HST, CFHT, and Spitzer data overlaid.

  • Black points (HST F110W) and red points (Spitzer IRAC1) are taken from Jonelle's paper
  • Purple points (CFHT) taken from Matthew's figures with a -0.95 magnitude constant offset applied to match up the middle portion of the galaxy
  • MGEs are taken right from Boizelle+21

• One thing that is strange to me:

  • In the N315 paper, Figure 1 shows MGE A in the upper right surface brightness plot, and this seems to disagree with Figure 4 which compares the three MGEs. I can't seem to get the same behavior in the inner portion of the MGEs as is claimed in FIgure 4? And it seems the black squares disagree between the two figures as well.

With that said, here's the updated plot:
