When combined with the nine systems having µ≥1.0"/yr and/or late spectral type from the initial phases of this effort, we find that 73 of the 150 total systems are moving faster than 0.5"/yr and are therefore new members of the classic Luyten Half-Second sample. These constitute a 21% increase in the sample of stars with µ≥0.5"/yr in the declination region searched, thereby comprising an important addition to this long-neglected region of the sky. Distance estimates are provided for the entire sample, based on a combination of photographic plate magnitudes and Two Micron All Sky Survey photometry, using the relations recently presented by Hambly et al. for the presumed main-sequence stars. Three systems are anticipated to be within 10pc, and an additional 15 are within 25pc. Nine of these 18 nearby systems have proper motions falling between 0.4"/yr and 0.6"/yr, hinting at a large population of nearby stars with fast, but not extremely high, proper motions that have not been thoroughly investigated. Description: Coordinates, proper motions, and plate magnitudes have been extracted from SuperCOSMOS (Hambly et al., 2001MNRAS.326.1279H) and are listed in table2.dat. Infrared photometry is used to extend the color baseline, which allows more accurate photometric distance estimates for red dwarfs and permits a fairly reliable separation of the white and red dwarfs. The infrared JHKs photometry has been extracted from the Two Micron All Sky Survey (2MASS, II/246) via Aladin. File Summary:
