 Description   

Normalize the best fit model spectrum flux to match the broad-band photometry of a standard before creating the flux calibration vector.

We do the absolute scaling using a weighted mean of an available broad-band photometry set. The scaled model spectrum is derived as follows:
 
f_scaled_model = f_model * (a weighted mean of observed broad-band fluxes) / (a weighted mean of the synthetic fluxes)

Comment by Takuji Yamashita [ 06/Jul/21 ]

The flux ratio of the absolute scaled model to the simulated spectrum is shown in PIPE2D-370, for example.
