C ****************** FORTRAN77 SUBROUTINE: BXDATA *********************
C
C PURPOSE: TO FETCH DATA FROM INPUT COPASE DATA SET.
C
C CALLING PROGRAM: ADAS205/ADAS206/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
