UV bump strength #329

Closed alexmaragko closed 2 months ago

alexmaragko commented 3 months ago

Is it possible to recover the UV bump strength from the dust_type=4 model, i.e., the Kriek & Conroy (2013) attenuation curve, or this is only possible through the uvb parameter in the dust_type=1 model?

Hi @alexmaragko, sorry for the delay. Fordust_type=4 the bump strength is related to the change in the slope of the curve relative to Calzetti (given by dust_index), so if you can calculate the slope from that. Basically equation 3 from Kriek & Conroy 2013 is coded directly:

E_b = 0.85 - 1.9 * dust_index

Assuming this is resolved, but please reopen if you have further questions about this.
