The Astrophysical Plasma Emission Database contains data for calculating the
continuum and emission line spectra of astronomical sources. The APED group
compiles the data and maintains the codes needed for these calculations.
Bob Kurucz maintains a large database of atomic and molecular linelists and
opacities for stellar atmosphere calculations. The database includes grids
of model atmospheres for the Sun and other stars.
Pandora is a general-purpose non-LTE computer program for calculating stellar atmosphere models and detailed line and continuum spectra.
The MPC is responsible for the designation of minor planets, comets, and natural
satellites in the solar system. The MPC is also responsible for the efficient
collection, computation, checking, and dissemination of astrometric observations
and orbits for minor planets and comets.
