; NAME:
;       phangs_make_isrf_product
; CALLING SEQUENCE:
;       phangs_make_isrf_product,source_name,voronoi_id,ISRFS,G0s,object_distance,object_thickness,help=help
; PURPOSE:
;       make and saves an ISRF product fits file
; INPUTS:
;       source_name,voronoi_id,ISRFS,G0s,object_distance,object_thickness,help=help
; OPTIONAL KEYWORDS:
;       save        = if set, save the classes
;       help        = if set, print this help
; OUTPUTS:
;	    None
; OPTIONAL INPUT:
;       
; OPTIONAL OUTPUT:
;       None
; PROCEDURE AND SUBROUTINE USED
;       ISRF saved is the one predicted by dustem_plugin_phangs_stellar_isrf for each Muse Voronoi bin,
;       scaled in amplitude to match the Muse filter data for that Voronoi bin.
;       The G0 value computed is wrt the Mathis field at 1 mic.
; SIDE EFFECTS:
;       produces file _isrf_min_prediction.fits
; EXAMPLE:
;       phangs_make_isrf_product,'ngc0628'
; MODIFICATION HISTORY:
;       written by Jean-Philippe Bernard
