;REMARKS: BECAUSE I STILL HAVEN'T SET THE DEFAULT VALUE FOR THE MAJORIY OF THE STELLAR POULATIONS, I WILL COMMENT THE CORRESPONDING LINES INSTEAD OF CHOOSING ARBITRARY VALUES. 


;CONSIDERED STARS: SPEC_TYPE(4) = OBAFG, LUM_CLASS(10) = IA+,IA,IAB,IB,II,III,IV,V,VI,VII 

;===========Initializing the defaut stellar population structure===========

;===========Counters===========

;===========Specifying whether to add the Mathis field (and its scaling via G0) to the composite ISRF===================
ismathis=0 ;this value will have to be manually changed at the present moment
defsysv, '!ismathis', ismathis
;====================================================================================================================== 


;===========Constants (in cgs)========== (except for the stellar population distance (in pc))
rsun2cm = 6.957e10 

;Stelar density constant to automate the computation of the number of stars. (It links the distance and the number of stars)
;The below stellar density will have to be modified as the density goes up towards the center, in globular clusters and goes down as we move out of the galactic plane
stellar_density = 0.14 ;stars/pc^3 stellar density in the SOLAR VICINITY     
;============================================================================================ 
 
;================NOTA BENE========================================================================== 
;KM are not included because I assumed that their UV part was not that important to excite the dust. 
;This will help ease and shorten the fitting procedure
