==== Everything you always wanted to know about Herb Pickett's spectroscopy programs but were afraid to ask ====

Well, I am sure that not all of your problems regarding Herb's programs will be solved after having gone through all the documentations and examples, but hopefully some aspects will have become a bit clearer.

While it is not necessary to be an expert in spectroscopy or pickettology in order to use his programs successfully a certain knowledge of spectroscopy and a tad of abstract thinking may be useful.

At some point later we intend to include information on some other programs that we are using . . .

=== Programs, examples, tips, and documentations ===

  * Herb Pickett's documentation for the {{:pdfs:calpgm.pdf |CALPGM program suite}} from July 20, 2004 with installation instructions and links to SPFIT/SPCAT and DPFIT/DPCAT. Several changes and corrections have been made; some of the major changes have been documented briefly.
  * Herb Pickett's documentation for {{:pdfs:spinv.pdf |SPCAT and SPFIT}} from April 26, 2006.
  * Herb Pickett's documentation for {{:pdfs:dpi.pdf |DPCAT and DPFIT}} from July 9, 2005.
  * Remarks on the [[coding|coding of the parameters]].
  * [[https://cdms.astro.uni-koeln.de/classic/predictions/pickett/beispiele|Examples for the SPFIT/SPCAT]] programs. Unfortunately, at present several README files are in German. Please send an e-mail to Holger Müller if you are in need of more details on the data, the fit, etc.
  * [[https://cdms.astro.uni-koeln.de/classic/predictions/pickett/quelle|Source codes]], Makefile etc., in general written in C. A zip file is also available.\\ **Nov. 2007**: New program versions are available. They have been tested to some extent. Care is advised with less commonly used features as there is a chance that they have not yet been tested with the most recent version. Background on the changes. Old source codes will still be available !

If you have any questions, comments, etc. please send an e-mail to Holger Müller: hspm(At)ph1(Dot)uni-koeln(Dot)de.
