SOFTWARE FOR DATA REDUCTION

We use original software for data reduction: the program MultiFit (M.F.T.) designed by J.-J.Plateaux.

Databases used by MuliFit:

  • HiTran
  • Geisa
  • Moles.dat

Parameters used by MultiFit:

  • Isotopic abundance.
  • Molecular weight.
  • Partition function parameters.
  • Foreign broadening.
  • Self-broadening.
  • Pressure line shift.

Another programs used for data reduction:

  • C.R.I. Parameters fitting for the Watson's Hamiltonian - Lines and intensities calculation.
  • T.S.T.D. Bands center and mixing coefficients prediction.
