# Fits Format

The input and output files for the separate fits performed with
SPFIT (H.M.Pickett, J.Mol.Spectrosc. 148,371-377(1991)) are provided.

The state identifiers tranlate to the vibrational modes as shown in
the following table.

      ID | Vibrational Mode
---------|-------------------
       1 | v_{21}=1
       2 | v_{21}=2
       3 | v_{21}=3
       4 | v_{21}=4
       5 | v_{21}=5
       6 | v_{21}=6
       7 | v_{21}=7
       8 | v_{20}=1
       9 | v_{19}=1
      10 | v_{18}=1
      11 | v_{21}=v_{20}=1
      12 | v_{21}=v_{18}=1
      13 | v_{21}=2, v_{20}=1
      14 | v_{21}=v_{19}=1
      15 | v_{20}=2
      16 | v_{20}=v_{19}=1
      17 | v_{21}=1, v_{20}=2
      18 | v_{21}=2, v_{19}=1

If multiple states are fit in a combined fit due to interactions,
the order of their ID's corresponds to the order of the states
in the corresponding *.par file.

For example the files named State_001 hold the model for v_{21}=1.
The files named State_003_009 hold the models for the combined
fit of v_{21}=3 and v_{19}=1.
v_{21}=3 corresponds in these files to the vibrational 
identifier 0 and v_{19}=1 to the vibrational identifier 1.
