meeting 2026 02 17 gw - JacobPilawa/TriaxSchwarzschild_wiki_6 GitHub Wiki
Context
- Adding some miscellanenous plots/thoughts/information following the meeting on Friday with Chung-Pei.
Diagnostics
- I've plotted the mass comparsions as a function of the LM24/Cappellari masses (instead of redshift), and here's what they look like:
| Nothing K-Corrected | Everything K-Corrected | WISE Only | K-band Only |
|---|---|---|---|

- I've also created versions of some of the plots we've seen before but comparing a larger set of the masses all against one another
| Everything K Corrected | Nothing K-Corrected | WISE Only | K-Band Only |
|---|---|---|---|

- And I have also done some preliminary "correction factor" work both as a function of redshift and as a function of mass:
- In these plots, I am showing the version where everything is k-corrected. I am simply fitting a line to the binned data and "correcting" the W1/W2 based masses to agree with the K-Band based masses.
- Putting these together just before the meeting so a few things I still need to check out with respect to these plots. But a few things immediately come to mind:
- 2MPZ doesn't go to as high of redshift; so do we just trust the correction outside of this? Do we assume a fixed stellar mass correction beyond the point where we have 2MPZ data?
Linear Version
- Coming soon! I quickly made a version which looked at the Cluver+14 only panel, which looks like:
| Cluver+14 Linear Version | Cluver+14 Clipped Linear Correction |
|---|---|

Cubic Version
- Running out of time before the meeting, but I had tried a version where I fit a cubic to this data and corrected it. Likely
