Default Target Selection for SETI. II.

Just noticed a paper by Turnbull & Tarter in the
Astrophys. J. Suppl. Series. The full article is available only to
subscribers, but here's the abstract


The Astrophysical Journal Supplement Series, 149:423-436, 2003

Target Selection for SETI. II. Tycho-2 Dwarfs, Old Open Clusters, and
the Nearest 100 Stars

Margaret C. Turnbull
Jill C. Tarter


ABSTRACT

We present the full target list and prioritization algorithm developed
for use by the microwave search for technological signals at the SETI
Institute. We have included the Catalog of Nearby Habitable Stellar
Systems (HabCat, described in Paper I), all of the nearest 100 stars
and 14 old open clusters. This is further augmented by a subset of the
Tycho-2 catalog based on reduced proper motions, and this larger
catalog should routinely provide at least three target stars within
the large primary field of view of the Allen Telescope Array. The
algorithm for prioritizing objects in the full target list includes
scoring based on the subset category of each target (i.e., HabCat,
cluster, Tycho-2, or nearest 100), its distance (if known), and its
proximity to the Sun on the color-magnitude diagram.

Subject headings: extraterrestrial intelligence---solar neighborhood
