C (ELECTRON IMPACT TRANSITIONS ONLY). C C CALLING PROGRAM: ADAS201 C C DATA: C THE 'REAL' DATA IN THE FILE IS REPRESENTED IN AN ABBREVIATED C FORM WHICH OMITS THE "D" OR "E" EXPONENT SPECIFIER. C e.g. 1.23D-06 or 1.23E-06 IS REPRESENTED AS 1.23-06 C 6.75D+07 or 6.75E+07 IS REPRESENTED AS 6.75+07 C C THEREFORE THE FORM OF EACH 'REAL' NUMBER IN THE DATA SET IS: C N.NN+NN or N.NN-NN C C THE UNITS USED IN THE DATA FILE ARE TAKEN AS FOLLOWS: C C IONISATION POTENTIAL: WAVE NUMBER (CM-1) C INDEX LEVEL ENERGIES: WAVE NUMBER (CM-1) C TEMPERATURES : KELVIN C A-VALUES : SEC-1 C GAMMA-VALUES : C RATE COEFFT. : CM3 SEC-1 C C C SUBROUTINE: C C INPUT : (I*4) IUNIT = UNIT TO WHICH INPUT FILE IS ALLOCATED C INPUT : (I*4) NDLEV = MAXIMUM NUMBER OF LEVELS THAT CAN BE READ C INPUT : (I*4) NDTRN = MAX. NUMBER OF TRANSITIONS THAT CAN BE READ C C OUTPUT: (C*3) TITLED = ELEMENT SYMBOL. C OUTPUT: (I*4) IZ = RECOMBINED ION CHARGE READ C OUTPUT: (I*4) IZ0 = NUCLEAR CHARGE READ C OUTPUT: (I*4) IZ1 = RECOMBINING ION CHARGE READ C (NOTE: IZ1 SHOULD EQUAL IZ+1) C OUTPUT: (R*8) BWNO = IONISATION POTENTIAL (CM-1) C C OUTPUT: (I*4) IL = INPUT DATA FILE: NUMBER OF ENERGY LEVELS C C OUTPUT: (I*4) IA() = ENERGY LEVEL INDEX NUMBER C OUTPUT: (C*12) CSTRGA()= NOMENCLATURE/CONFIGURATION FOR LEVEL 'IA()' C OUTPUT: (I*4) ISA() = MULTIPLICITY FOR LEVEL 'IA()' C NOTE: (ISA-1)/2 = QUANTUM NUMBER (S) C OUTPUT: (I*4) ILA() = QUANTUM NUMBER (L) FOR LEVEL 'IA()' C OUTPUT: (R*8) XJA() = QUANTUM NUMBER (J-VALUE) FOR LEVEL 'IA()' C NOTE: (2*XJA)+1 = STATISTICAL WEIGHT C OUTPUT: (R*8) WA() = ENERGY RELATIVE TO LEVEL 1 (CM-1) FOR LEVEL C 'IA()' C C OUTPUT: (I*4) NV = INPUT DATA FILE: NUMBER OF GAMMA/TEMPERATURE C PAIRS FOR A GIVEN TRANSITION. C OUTPUT: (R*8) SCEF() = INPUT DATA FILE: ELECTRON TEMPERATURES (K) C (INITIALLY JUST THE MANTISSA. SEE 'ITPOW()') C (NOTE: TE=TP=TH IS ASSUMED) C C OUTPUT: (I*4) ITRAN = INPUT DATA FILE: NUMBER OF ELECTRON IMPACT C TRANSITIONS. C C OUTPUT: (I*4) I1A() = ELECTRON IMPACT TRANSITION: C LOWER ENERGY LEVEL INDEX C OUTPUT: (I*4) I2A() = ELECTRON IMPACT TRANSITION: C UPPER ENERGY LEVEL INDEX C OUTPUT: (R*8) AVAL() = ELECTRON IMPACT TRANSITION: C A-VALUE (SEC-1) C OUTPUT: (R*8) SCOM(,) = ELECTRON IMPACT TRANSITION: C GAMMA VALUES C 1ST DIMENSION - TEMPERATURE 'SCEF()' C 2ND DIMENSION - TRANSITION NUMBER C C (I*4) NDTEM = PARAMETER = MAX NUMBER OF INPUT FILE TEMPS.
