I found there is an obvious difference in W3 transmit curves between pyphot and SVO. This difference affects the conversion from spectrum to synthetic photometry. I don't know which curve is correct. …

Synthetic photometry is done now in a pretty crude way using tophat approximations for the filter transmission curves of e.g. the Spitzer IRAC and MIPS filters. This can be done m…

Are the HST + JWST filter throughput curves you used for the synthetic photometry available somewhere in the JADES data release?
Thanks!

We have been looking in detail at the photometry from our Oculus Pro Camera (Starlight Xpress) with 150 deg FOV.
For exposure times greater than 1 sec the light entering the camera from an apparent m…

@kilohoku - I see some JHK measurements in the "2MASS" columns which don't appear to be 2MASS sources. Are the majority of these from a particular instrument/telescope that is not 2M…

When computing synthetic photometry with Filter().obj_counts, need to catch and better treat the case where the source spectrum is significantly lower resolution than the transmission curve.
In thi…

@robelgeda mentioned that it would be useful for `synphot.units` to be separated out from this package, so others can take advantage of the flux unit conversion even if they are not interested in synt…

Try adding a boring elliptical galaxy to the tutorial to see if its synthetic photometry is also biased in the same direction as the emission line galaxy example. This will be diagnostic: if the borin…

If simultaneously fitting the stellar and extinction, it would be good to do this with a composite model.
For example, assume a blackbody for the stellar and one of the dust_extinction models. Need …
