[PHOEBE-discuss] custom passband request

[Man C. A. Li <ml...@au...>]

Dear PHOEBE developers,

I am a PhD student working on MOA (Microlensing on Astrophysics) group.

I want to perform the light curve fitting of MOA eclipsing binary
candidates with PHOEBE. Unfortunately, MOA uses a non-standard passband
which is not included in the PHOEBE's passband list, so I request for the
help to generate the MOA passband fits and required tables.

I have read through the webpage, but I am still confused how to do the
fitting with a custom passband. For example, when I set lcdep and rvdep,
what should I change to make it work with a custom passband?

lcdep = phoebe.ParameterSet('lcdep', passband='KEPLER.V', atm='kurucz',
                            ld_func='claret', ld_coeffs='kurucz',
ref='my kepler lc')rvdep = phoebe.ParameterSet('rvdep',
passband='JOHNSON.V', atm='kurucz',
                            ld_func='claret', ld_coeffs='kurucz')

In addition, since MOA observations measure the relative flux (flux
difference), is PHOEBE capable of fitting a light curve in relative flux?
Or is it required to convert the relative flux to the absolute flux or mag?

Regards,
Alex
