SPECTRUM ((C) Richard O. Gray, 1992,3,4,5) is a stellar spectral
synthesis program. SPECTRUM computes the LTE synthetic spectrum given a
stellar atmosphere model.
SPECTRUM uses as input the new, fully blanketed stellar atmosphere
models of Robert Kurucz (1991), but any other stellar atmosphere models
which can be cast into the format of
Kurucz's models can be used as well.
SPECTRUM can be programmed with "command-line switches" to give a
number of different outputs. In the default mode, SPECTRUM computes the
normalized-intensity spectrum, but in addition, SPECTRUM will
compute the absolute monochromatic flux from the stellar atmosphere or
the specific intensity from any point on the
SPECTRUM and a number of auxiliary programs can be run under batch
mode, making automated computation of a large number of synthetic
SPECTRUM is distributed with an atomic and molecular line list for
the optical spectral region 3000 A to 6800 A, called luke.lst suitable
for computing synthetic spectra with
temperatures between about 4500K and 20,000K.
SPECTRUM currently supports most atomic elements important in
stellar spectra and their first or second ions. SPECTRUM also supports
the following diatomic molecules: CH, NH,
OH, MgH, SiH, CaH, SiO, C2, CN, CO and TiO. Other molecules and
atoms will be added in the future.
