Context

  • A few very brief notes on this bullet:
    • Applied mass cut to the catalog, retaining only galaxies with Mcluver > 1e8 Msun
    • Attempting to do orthogonal distance regression instead of OLS -- this seems to better capture the overall trend, rather than being pulled down by a non-uniform density of points.
    • Added a few plots showing contours rather than scatter points which make the high density regions a bit more clear, I think.
    • Cleaned up mass difference plot, and have one plot comparing M/L from Kettlety+17 vs. our M/L distribution.

Updated Mass Comparison Plot

  • I tried to create a "beautified" version of a plot showing the mass differences for the paper, and think I landed on something nice. Note that this uses the updated K-band joint relation, and the catalog has 1e8 Msun galaxies and lower removed:

  • I also have a non-beautified version of another plot that might be worth showing. In GLADE+, they assume (for passive galaxies) a fixed M/L derived from Kettlety+18. I've created a plot showing our M/L distribution relative to this single value that Kettlety+18 derived.

    • Note I am excluding the lowest M/L bin from the plot here -- the Cluver routine "clips" W1-W2 color, leading to a hard-edge at low M/L values in this plot. The mean/median doesn't appreciably change, but if I include this population, there's a huge histogram bin at low masses. We can decide what to do about that later:

Joint K-Band Relation Plot

  • Switched to a pivot point of M_k = -25.6. The updated K-band relation looks like this:
