Add Gaia MAW MIST magnitudes #99

Closed segasai closed 5 years ago

segasai commented 5 years ago

Hi, Timothy,

MIST isochrones for Gaia now have magnitudes using the updated sensitivity curves from 1808.02820 (called Gaia_G_MAW,... ) This patch allows them to be accessed through isochrones.

Thanks for this! Does this work? Do you mind adding a test somewhere initializing an isochrone with these bands? e.g.,

mist = get_ichrone('mist', bands=['Gaia_G_MAW', 'Gaia_BP_MAWf', 'Gaia_BP_MAWb', 'Gaia_RP_MAW'])
mist.initialize()

Great, thanks! Will merge when passes.

And just to make sure I understand the context here; these are recalibrated bandpasses that should be better than the default/originals, right? Is it maybe worth making these the default when users ask for gaia bandpasses? What do you think?

segasai commented 5 years ago

Yes, those those should be better AFAIU https://arxiv.org/pdf/1808.02820.pdf . I haven't done any indepedent validation myself though. I wouldn't make those bands default now though.

Great, thanks for the insight!
