issue with adding a JWST/MIRI photometric band when generating a model galaxy spectrum? #218

Closed Vladan1986 closed 2 years ago

Vladan1986 commented 2 years ago

Hello,

I have an issue when I want to generate a model galaxy spectrum with predictions for photometric fluxes for an example galaxy with HST and JWST filters.

When I add all the available filters for this galaxy, including the MIRI F770W filter (in the attachment) I obtain 1 data point that seems to be <1 in the x axis log space, so lambda seems to be negative (Fig. 2). If I remove the F770W filter, I obtain Fig. 1.

I tried removing the 0 and < 10^{-11} flux values from the F770W throughput values, but that didn't solve the issue. Any suggestion or help is welcome.

Cheers,

This does not seem related to pymultinest at all. Try to simplify your problem.
