AgeWizard bias for densely populated regions of the HR diagram [FEATURE]

Open AlexandreLegault opened this issue 1 year ago • 1 comments

AgeWizard appears to be bias when yielding a most probable age when the bulk of a population occupies the same bins of a HR diagram, regardless of the contribution of scarcer stars farther along the isocontours. Is there a way to unbias the AgeWizard tool so that it reduces the contribution of overlapping objects?

Inspection of each member's PDF for physical interpretation can do the trick for now, but a weighting system could be interesting! Thanks!

Thanks for opening this issue. If anyone else is reading up on this as they are using age wizard, here is the current bias that exists:

AgeWizard can misinterpret stars that are on the turn off point as being MS of a lower age population that has MORE stars there. As a result AgeWizard will tend to OVERESTIMATE the age of a population.

This project is on the back burner but there should be away to apply a scaling to the stars such that this bias is being accounted for.
