DustValues¶
- class rubin_sim.phot_utils.DustValues(r_v=3.1, bandpass_dict=None, ref_ebv=1.0)¶
Bases:
objectCalculate extinction values
- Parameters:
- R_vfloat (3.1)
Extinction law parameter (3.1).
- bandpassDictdict (None)
A dict with keys of filtername and values of rubin_sim.phot_utils.Bandpass objects. Default of None will load the standard ugrizy bandpasses.
- ref_evfloat (1.)
The reference E(B-V) value to use. Things in MAF assume 1.
- Note: the value that dust_values calls “ax1” is actually equivalent to r_x in any filter.
- And then it’s more clear that r_x * ebv = A_x (the extinction due to dust in any bandpass).
- DustValues.r_x is also provided as a copy of DustValues.ax1 .. eventually ax1 may be deprecated
- in favor of r_x.
