Meeting the Cool Neighbors. II. Photometry of Southern NLTT Stars

We present BVRI photometry of 180 bright, southern nearby-star candidates. The stars were selected from the New Luyten Two-Tenths proper-motion catalog based on optical/infrared colors, constructed by combining Luyten's m_r estimates with near-infrared photometry from the Two Micron All Sky Survey. Photometric parallaxes derived from V-K_s, V-I, and I-J colors, combined with the limited available astrometry, show that as many as 108 stars may lie within 20 pc of the Sun. Of these, 53 are new to nearby-star catalogs, including three within 10 pc of the Sun.
