This is a preliminary version of a document which will hopefully evolve into a useful SCIENCE HELP page. This is meant to be an easily accessed directory of science software and data products which are available in the high energy division, primarily those which are maintained by "volunteer" scientists. ... The idea is to make this a cooperative venture - this document can be edited by anyone on the HEAD network (/proj/qedros2/QEDT/www/Science_guide/science_guide.html). ... LOCATION: /soft/ciao . ...

... spectrum . ... The photons we detect originate in the outermost layers, or atmosphere, of the star. In order to interpret stellar spectra, it is necessary to construct models which accurately represent the structure of a stellar atmosphere and the transfer of radiation from the stellar interior into interstellar space. For the study of helium stars and other stellar remnants, we in Armagh use several computer programs, of which sterne and spectrum are the most important. sterne . ...
