====== On the Coding of the Parameters ======

Well, the coding of the parameters in Herb Pickett's programs is an interesting issue. Herb has come up with a
rather logical solution. However, the logic might seem a tad tricky for someone beginning to use Herb's programs.
Herb has some[[general| general remarks]] on the coding of the parameters and [[general#simple_examples|some simple examples]] in
his documentation. Further information is availabale in the name files for some specific spectroscopy problems.

[[https://cdms.astro.uni-koeln.de/classic/predictions/pickett/spina.nam|spina.nam]] describe the
codes for an asymmetric top in Watson's S and A reduction, respectively. More codes are in the files

molecules without and with one unpaired electron, respectively.
