Abstract:
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 25pc 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 0.9m 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.
Description:
We have developed a list of 1748 southern (δ≤0°) stellar
systems containing M dwarf primaries.
Plate magnitudes from SuperCOSMOS are given in Table 1 for all but a
few systems and are rounded to the nearest hundredth magnitude. The
wavelength ranges for the BJ, R59F, and IIVN filters are
3950-5400Å, 5900-6900Å, and 7150-9000Å, respectively (Morgan,
1995ASPC...84..137M 1995ASPC...84..137M, p137).
We have measured Johnson-Kron-Cousins VJRKCIKC photometry (the
central wavelengths for the VJ(old), VJ(new), RKC, and IKC
filters are 5438, 5475, 6425, and 8075Å, respectively. See Jao et
al., 2011AJ....141..117J 2011AJ....141..117J, for a discussion of the nearly identical
VJ(old) and VJ(new) filters) for 799 of the systems presented here
as a part of our astrometry/photometry program, primarily at the Cerro
Tololo Inter-American Observatory (CTIO)/SMARTS 0.9m, with a few
measurements from the CTIO/SMARTS 1.0m (see Jao et al.,
2005AJ....129.1954J 2005AJ....129.1954J, Henry et al., 2006AJ....132.2360H 2006AJ....132.2360H for details on
the astrometry; see Winters et al. 2011, cat. J/AJ/141/21, for details
on the photometry). The observations were made between 1999 and 2013.

Note (1): All proper motions are from SuperCOSMOS, except where noted. Some of
the proper motion values from the SuperCOSMOS Sky Survey for SCR objects
presented here differ slightly from those in the original discovery papers.
For the new values, a more comprehensive method has been used that provides
multiple measurements of proper motion between various plate pairs, while
before only a single value was available that incorporated all plates into
the solution simultaneously. The proper motions provided here are those
that yield consistent values among multiple determinations and are
preferred.
Note (2): Flag on parallax defined as follows:
a = The weighted mean parallax includes the parallax of both the primary and
the secondary components;
b = The HIP parallax is markedly different from that published in the Yale
Parallax Catalog (YPC; Also called The General Catalogue of Trigonometric
Stellar Parallaxes, Fourth Edition, van Altena 1995, cat. I/174) and has
an error of ∼45mas.
Note (3): The wavelength ranges for the BJ, R59F, and IIVN filters are
3950-5400Å, 5900-6900Å, and 7150-9000Å, respectively (Morgan,
1995ASPC...84..137M 1995ASPC...84..137M, p137). See Section 3.1 for more details about the
BJR59FIIVN plate photometry. The plate R59F magnitude is the
second, more recent R epoch measurement of the two available in the
SuperCOSMOS Sky Survey.
Note (4): Primarily the VJ, RKC, IKC magnitudes measured by REsearch
Consortium On Nearby Stars (RECONS; http://www.recons.org/) group at Cerro
Tololo Inter-American Observatory (CTIO) and the number of observations,
or VRI from a trusted source. The central wavelengths for the VJ(old),
VJ(new), RKC, and IKC filters are 5438, 5475, 6425, and 8075Å,
respectively. See Jao et al., 2011AJ....141..117J 2011AJ....141..117J, for a discussion of the
nearly identical VJ(old) and VJ(new) filters. See Section 3.2 for more
details about the VJRKCIKC CCD photometry.
Note (5):
u = We have previously published photometry for this object, but have since
then acquired more data and updated the value.
Note (6): Flag on 2MASS magnitude defined as follows:
J = Indicates that light from a close companion has resulted in blended

Note (7): Calculated by combining SuperCOSMOS BRI photometry with 2MASS infrared
photometry via a suite of 15 color-MK relations using BRIJHK, as
described in Hambly et al. (2004AJ....128..437H 2004AJ....128..437H). See Secion 4.1 for
additional details.
Note (8): The flags on distance are defined as follows:
c = Confirmed or candidate subdwarf (distance typically closer than estimated);
f = Distance based on blended photometry (distance typically further than
estimated).
Note (9): Determined using a method similar to that used for the plate derived
distances and as described by Henry et al. (2004AJ....128..437H 2004AJ....128..437H). The
difference is that we use more accurate CCD VRI magnitudes obtained at
Cerro Tololo Inter-American Observatory (CTIO) instead of plate magnitudes
from SuperCOSMOS to determine the suite of color-MK relations.
See Secion 4.2 for more details.

Global notes:
Note (G1): The table is divided into the 1404 systems within 25pc at the top
and the 344 systems beyond 25pc on the bottom. We refer to any collection
of stars and their companion brown dwarfs and/or exoplanets as a system,
including single M dwarfs not currently known to have any companions.
Systems that contain a white dwarf component have been omitted, as the
white dwarf was initially the brighter primary component.
