Icochrone fitting (todo list)

 Next steps to explore the simplified isochrone fitting code

To-Dos

Code changes / updates / tests

• use finer grids at <1 Gyrs
• understand whether the original Teff really needs to be modified, and why
• understand why the isochrones > 13 Gyrs give "funny" results
• the CMD distribution of stars identified as 8 < logAge < 8.5 looks funny
• I set a floor to the precision of the photometry; was that bad?
• conceptually, we still need to work out how to make all this "mass weighted"
• consider ingesting a prior on each star's extinction

Diagnostic plots

• look at the CMD distribution of stars in a grid of (FE_H and fitlogAge); what looks OK?
• look at the "tensions" between input and output: are there systematic differences between the input FeH, Teff, G and the best fit predictions of the isochrones?  
  Note: this requires that we also calculate the likelihood-weighted mean of the isochrone predictions, not only of the isochrone's "physical parameters"
