Abstract (from CDS):

We present trigonometric, photometric, and photographic distances to 1748 southern (δ ≤ O°) M dwarf systems with µ ≥ 0".18/yr, of which 1404 are believed to lie within 25 pc of the Sun. The stars have 6.67 ≤ VJ ≤ 21.38 and 3.50 ≤ (VJ - KS) ≤ 9.27, covering the entire M dwarf spectral sequence from M0.0 V through M9.5 V. This sample therefore provides a comprehensive snapshot of our current knowledge of the southern sky for the nearest M dwarfs that dominate the stellar population of the Galaxy. Roughly one-third of the 1748 systems, each of which has an M dwarf primary, have published high quality parallaxes, including 179 from the REsearch Consortium On Nearby Stars astrometry program. For the remaining systems, we offer photometric distance estimates that have well-calibrated errors. The bulk of these (∼ 700) are based on new VJRKCIKC photometry acquired at the CTIO/SMARTS 0.9 m telescope, while the remaining 500 primaries have photographic plate distance estimates calculated using SuperCOSMOS BJR59FIIVN photometry. Confirmed and candidate subdwarfs in the sample have been identified, and a census of companions is included.
