Stellar Population Outputs#

Note

We define additional array size variables here for convenience. (See here for the already defined array size variables.)

Nsteps : the number of chosen SFH age bins (or steps).

LNU_STARMODdouble array(Nfilters, Nmodels): The stellar population contribution to the mean \(L_\nu\) in each filter, after reddening by the dust attenuation model \([L_\odot\ {\rm Hz}^{-1}]\).
LNU_STARMOD_UNREDdouble array(Nfilters, Nmodels): The intrinsic stellar population contribution to the mean \(L_\nu\) in each filter, with no reddening by the dust attenuation model \([L_\odot\ {\rm Hz}^{-1}]\).
LNU_STARMOD_HIRESdouble array(1000, Nhighres_models): The stellar population contribution to the total high resolution UV-to-FIR luminosities, after reddening by the dust attenuation model \([L_\odot\ {\rm Hz}^{-1}]\).
LNU_STARMOD_UNRED_HIRESdouble array(1000, Nhighres_models): The intrinsic stellar population contribution to the total high resolution UV-to-FIR luminosities, with no reddening by the dust attenuation model \([L_\odot\ {\rm Hz}^{-1}]\).
STEPS_BOUNDSdouble array(Nsteps + 1): The bounds on the age bins of the star formation history \([{\rm yr}]\).
MSTARdouble array(Nmodels): The total surviving stellar mass \(M_{\star}\) in \(\rm M_\odot\) produced by the resulting SFH.
MSTAR_UNCdouble array(Nmodels): The estimated \(1\sigma\) uncertainty for the total stellar mass in \(\rm M_\odot\).

Note

Only appears in the output if using the MPFIT algorithm.
STEPS_MSTARdouble array(Nsteps, Nmodels): The surviving stellar mass components \(M_{\star,i}\) in \(\rm M_\odot\) produced by each age bin \(i\) of the star formation history. The total stellar mass \(M_{\star}\) is then

\[M_{\star} = \sum_i M_{\star,i}.\]
STEPS_MSTAR_UNCdouble array(Nsteps, Nmodels): The estimated \(1\sigma\) uncertainty for the surviving stellar mass components in \(\rm M_\odot\).

Note

Only appears in the output if using the MPFIT algorithm.
