compute and include rest-frame photometry #32

Open moustakas opened 4 years ago

moustakas commented 4 years ago

Related to #21, it was suggested by @paulmartini to include the rest-frame (absolute) photometry, as a tool for assessing the redshift (particularly for the QSOs).

@moustakas I want to implement this (and other) additional meta-data in the viewer now. How do you get this rest-frame photometry ?

from the GRZW photometry and the redshift from pipeline, using a linear combination depending on the central wavelength of each filter?
from the measured spectra themselves, by integrating over the band covered by the redshifted filter ?
another way?

Thanks for re-raising this issue, @armengau.

I'm working on some relevant code that may work well as a redrock after-burner and which we can use to load rest-frame quantities into prospect. I'll have some updates here soon.

@moustakas, what are the next steps on the prospect side? Presumably, prospect would need an additional input of values from fastspecfit, which would require access to the fastspecfit files, etc.

There are no updates on this ticket, but I think it should remain open. K-corrections and rest-frame quantities would need to be computed as an afterburner to the pipeline (since prospect works on the daily reductions), but there is no effort at the moment to incorporate this.

That's fine, thanx for the update!
