C
C  Purpose:  Distribute Doppler broadened line emission into pixel range
C
C  Calling program: adas305, stark
C
C
C  Subroutine:
C
C  input : (i*4)  ndpix   = maximum number of pixels
C
C  input : (i*4)  npix    = number of pixels assigned to wavelength interval
C  input : (r*8)  wvmin   = lower limit of wavelength interval (ang)
C  input : (r*8)  wvmax   = upper limit of wavelength interval (ang)
C
C  input : (r*8)  cpixmx  = largest pixel count currently found
C                           for the wavelength range
C
C  input : (r*8)  tev     = electron temperature (eV)
C  input : (r*8)  amssno  = atomic mass number
C  input : (r*8)  wvl     = input line wavelength for test(ang)
C  input : (r*8)  pec     = emissivity coefficient for component
C
C  output: (r*8)  cpixa() = counts in each pixel for the line
C  output: (r*8)  ind1    = first pixel with non-negligible count
C  output: (r*8)  ind2    = last pixel with non-negligible count
C
C          (r*8)  fcrit   = pixel counts for the selected line below
C                           this fraction of the largest pixel count are
C                           discounted.
