SPnKr
A tool for determining the properties of stars.
This program is designed to determine the correct parameters of a model atmosphere of a star through iterative refinement and measurements of spectral absorption lines.
**Correction: It appears that what I termed "iterative refinement" has already been named "Predictor-Corrector" by the Mathematical Community.**
Regrettably, this program still depends on a few other programs, namely SuperMONGO (http://www.astro.princeton.edu/~rhl/sm/sm.html though this page is fairly old, you may need...
