Abstract (from CDS):

We present CCD photometric distance estimates of 100 SCR (SuperCOSMOS RECONS) systems with µ ≥ 0".18/yr, 29 of which are new discoveries previously unpublished in this series of papers. These distances are estimated using a combination of new VRI photometry acquired at CTIO and JHK magnitudes extracted from 2MASS. The estimates are improvements over those determined using photographic plate BRI magnitudes from SuperCOSMOS plus JHK, as presented in the original discovery papers. In total, 77 of the 100 systems investigated are predicted to be within 25 pc. If all 77 systems are confirmed to have π_trig≥ 40 mas, this sample would represent a 23% increase in M dwarf systems nearer than 25 pc in the southern sky.
