;DATA IS NOW RETRIEVED FROM THIS TEXT FILE: "A Modern Mean Dwarf Stellar Color and Effective Temperature Sequence"  
;NB: intermediate spectral classes '.5' are not taken into account - this will probably have to change
;NB: Also contact we need to contact the reasercher who wrote the text file because he said so in it.
;Other luminosity classes Should be included (only MS so far). 
;BB approximation is a first degree 'bad' approximation because of the lack of radiative transfer especially at the 
;photosphere of stars. 
;REMARKS: BECAUSE WE STILL HAVEN'T SET THE DEFAULT VALUE FOR THE MAJORIY OF THE STELLAR POULATIONS,THE CORRESPONDING LINES ARE COMMENTED INSTEAD OF SETTING ARBITRARY VALUES. 
;CONSIDERED STARS: SPEC_TYPE(N=5) = OBAFG, LUM_CLASS(N=10) = IA+,IA,IAB,IB,II,III,IV,V,VI,VII 
;KM spectral types are not included because their UV part was not that important to excite the dust.
;This will help ease and shorten the fitting procedure
;If the user wants to use them without having to read the entirety of this plugin please contact the DustEmWrap team.
