PROGRAM dParFit16
c***********************************************************************
c** Program "D(iatomic)Par(ameter)Fit" (DParFit) performs least-squares
c fits of a data set made up of any combination of MW, IR or electronic
c vibrational bands, PAS data, fluorescence series and/or Bv values,
c involving one or more singlet or doublet-sigma electronic states and
c one or more isotopomers, to parameters defining the observed levels
c of each state. Those levels may be described by band constants {Gv,
c Bv, Dv, etc.}, by Dunham expansions, by Near-Dissociation Expansions
c (NDE's), or by Tellinghuisen's mixed Dunham/NDE 'MXS' functions, and
c different expressions may be used for different states, while Lambda
c or spin-rotation doubling is described by band constants or by Dunham-
c type expansions in (v+1/2). Dunham, NDE or MXS function fits
c automatically take account of normal (1'st order semiclassical) multi-
c isotopomer mass scaling, and allow for inclusion of atomic-mass-
c dependent Born-Oppenheimer and 1'st order JWKB breakdown corrections
c (collectively called BOB corrections).
