[PIPE2D-1053] Make a full fluxmodeldata package

Fri, 24 Jun 2022 01:21:54 +0000

In ~~PIPE2D-920~~, we made what we call "6k fluxmodeldata", which contained ~ 6,000 spectra from AMBRE synthetic spectra. We now have to make "60k fluxmodeldata": ~60,000 spectra with their parameters on the finer grid that Yamashita-san's plan requires.

1. We have to extend the format of broadband/photometries.fits so that its user can distinguish the spectra in the 6k package from the other interpolated spectra.

2. We have to make a 60k package. We may include in it a file that indicates the hyperparameters used in interpolating the spectra.

3. We have to modify makeFluxModelInterpolator.py so that it will be aware of the new format of broadband/photometries.fits, and it will make interpolator.pickle only from the 6k spectra. I think we should not include interpolator.pickle in the package but each user should run makeFluxModelInterpolator.py to make it, because the pickle depends on scipy's version.

I will make the first version of 60k package with the hyperparameters already known to work reasonably. I think I can find better hyperparameters by estimating the goodness of hyperparameters with cross validation, but that will be another issue.
