SUBROUTINE INILIN_grid C ====================== C C read in the input line list, C selection of lines that may contribute, C set up auxiliary fields containing line parameters, C C Input of line data - unit 19: C C For each line, one (or two) records, containing: C C ALAM - wavelength (in nm) C ANUM - code of the element and ion (as in Kurucz-Peytremann) C (eg. 2.00 = HeI; 26.00 = FeI; 26.01 = FeII; 6.03 = C IV) C GF - log gf C EXCL - excitation potential of the lower level (in cm*-1) C QL - the J quantum number of the lower level C EXCU - excitation potential of the upper level (in cm*-1) C QU - the J quantum number of the upper level C AGAM = 0. - radiation damping taken classical C > 0. - the value of Gamma(rad) C C There are now two possibilities, called NEW and OLD, of the next C parameters: C a) NEW, next parameters are: C GS = 0. - Stark broadening taken classical C > 0. - value of log gamma(Stark) C GW = 0. - Van der Waals broadening taken classical C > 0. - value of log gamma(VdW) C INEXT = 0 - no other record necessary for a given line C > 0 - next record is read, which contains: C WGR1,WGR2,WGR3,WGR4 - Stark broadening values from Griem (in Angst) C for T=5000,10000,20000,40000 K, respectively; C and n(el)=1e16 for neutrals, =1e17 for ions. C ILWN = 0 - line taken in LTE (default) C > 0 - line taken in NLTE, ILWN is then index of the C lower level C =-1 - line taken in approx. NLTE, with Doppler K2 function C =-2 - line taken in approx. NLTE, with Lorentz K2 function C IUN = 0 - population of the upper level in LTE (default) C > 0 - index of the lower level C IPRF = 0 - Stark broadening determined by GS C < 0 - Stark broadening determined by WGR1 - WGR4 C > 0 - index for a special evaluation of the Stark C broadening (in the present version inly for He I - C see procedure GAMHE) C b) OLD, next parameters are C IPRF,ILWN,IUN - the same meaning as above C next record with WGR1-WGR4 - again the same meaning as above C (this record is automatically read if IPRF<0 C C The only differences between NEW and OLD is the occurence of C GS and GW in NEW, and slightly different format of reading.
