# The computation of spectra is described in Laigle, Davidzon, Ilbert+2019   #
# and Davidzon+2019. They are extracted from the Horizon-AGN simulation	     #
# described in Dubois et al. 2014.    	     	      		  	     #
# Please cite these 3 papers if you use these spectra.			     #
# Would you have any question on these spectra, please contact:  	     #
# clotilde.laigle@iap.fr and iary.davidzon@nbi.ku.dk                         #

# These spectra include dust attenuation and IGM absorption (Lyman-serie).   #

#/!\ /!\ /!\ /!\ /!\ /!\ /!\ CAUTION /!\ /!\ /!\ /!\ /!\ /!\ /!\ /!\ /!\ /!\ #
#/!\ The dust attenuation model only takes into account absorption and   /!\ #
#/!\ does not include scattering or re-emission.In addition, we do not   /!\ #
#/!\ put any constrain on the UV escape fraction beyond dust absorption  /!\ #
#/!\ (neutral gas absorption and scattering in the ISM is not modelled). /!\ #
#/!\ THE UV flux is therefore over-estimated!          	      		 /!\ #
#/!\ Nebular emission lines are not modelled. 				 /!\ #

#-------------------- DESCRIPTION OF THE FILES ------------------------------#
# 		   						             #
# Spectra are provided at 1132 wavelength steps from 506 to 1e+05 Angstroms, #
# for all the galaxies in HorizonAGN_LAIGLE-DAVIDZON+2019_COSMOS_v1.5.fits   #
#									     #
# To avoid manipulating very heavy files, spectra are distributed in 2 fits  #
# (MEF): HorizonAGN_LAIGLE-DAVIDZON+2019_SPECTRA_z0-2.fits for 0<z<2 and     #
#  HorizonAGN_LAIGLE-DAVIDZON+2019_SPECTRA_z0-2.fits for 2<z<4.	     	     #
# rest-frame log flux (in erg/s/cm^2/A) at 10 pc of the source are stored in #
# the second extension and lambda steps (in A) in the third extension.       #
#									     #
# ----------------FROM REST-FRAME TO OBSERVED SPECTRA----------------------- #
#									     #
# To convert the rest-frame spectra in the observer frame, you should 	     #
# multiply the wavelength steps by (1+z), where z is the redshift of the     #
# source (column "z" in  HorizonAGN_LAIGLE-DAVIDZON+2019_SPECTRA_zX-Y.fits)  #
# and multiply the flux values by 1./((1+z)*D^2), where D^2 is the luminosity#
# distance (column "D" in HorizonAGN_LAIGLE-DAVIDZON+2019_SPECTRA_zX-Y.fits) #
