J/AJ/141/21        CCD distance estimates of SCR targets        (Winters+, 2011)

The solar neighborhood. XXIII. CCD photometric distance estimates of SCR targets. 77 M dwarf systems within 25 pc. Winters J.G., Henry T.J., Jao W.-C., Subasavage J.P., Finch C.T., Hambly N.C. <Astron. J., 141, 21 (2011)> =2011AJ....141...21W
ADC_Keywords: Stars, nearby ; Proper motions; Photometry, infrared ; Stars, distances Keywords: solar neighborhood - stars: distances - stars: low-mass - stars: statistics - techniques: photometric Abstract: 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distance estimates of 100 SCR (SuperCOSMOS RECONS) systems with µ≥0.18"/yr, 29 of which are new discoveries previously unpublished in this series of papers.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 25pc. File Summary:

Global Notes: Note (G1): Coordinates are epoch and equinox 2000.0 using SuperCOSMOS positions transformed to epoch 2000.0 using the proper motions and position angles listed here; if AB, photometry or spectral type is for the system, i.e., joint. In the case of SCR0214-0733, no B plate magnitude was available in SuperCOSMOS.
