# Catalog of known extrasolar planetary systems.
#
# Most of the data in here was compiled from the Extrasolar Planets Catalog
# at http://www.obspm.fr/encycl/catalog.html.
#
# In most places, I've just used M sin i as the mass for the planets, though in a few
# cases I've used used astrometric estimates from [1].  The only orbital elements I've
# included are period, semi-major axis, and eccentricity.  Something else such as a time
# and longitude of periastron would be nice to bring the orbital motions of these planets
# closer in touch with reality, but I can't find any data.  The radii of the planets are
# very rough guesses based on mass, and in most cases are land quite close to
# Jupiter's radius.  I know that models exist for the radius of a gas giant as a function
# of mass, and I'd like to find and use one so there's at least slightly more rigor
# in this area.
#
# Here's how I classify 'planets' by mass:
#     0.1 - 11 Jupiter masses: gas giant
#     11 - 80 Jupiter masses: brown dwarf
#     > 80 Jupiter masses:    M class star

#     Preliminary astrometric masses for proposed exrasolar planetary companions.
#     ApJ. Letters, accepted



# Ups Andromeda system detected by Marcy, Butler et al using
# radial velocity method.
#
# Masses are all M sin i, though Han et al claim a preliminary
# mass of 10Mj for Ups And d based on astrometric data.
