Abstract:
We report 1606 new proper-motion systems in the southern sky
(declinations -90° to -47°) with 0.40"/yr>µ≥0.18"/yr. This
effort is a continuation of the SuperCOSMOS-RECONS (SCR) proper-motion
search to lower proper motions than reported in Papers VIII, X, XII,
and XV in this series. Distance estimates are presented for the new
systems, assuming that all stars are on the main sequence. We find
that 31 systems are within 25pc, including two systems (SCR 0838-5855
and SCR 1826-6542) that we anticipate to be within 10pc. These new
discoveries constitute a more than 10-fold increase in new systems
found in the same region of sky searched for systems with
mu≥0.40"/yr, suggesting a happy hunting ground for new nearby slower
proper-motion systems in the region just north (declinations -47°
to 0°), much of which has not been rigorously searched during
previous efforts.
Description:
The SCR search uses four of the Schmidt survey photographic plates
available in each ESO/SRC survey field, which provide astrometric and
photometric information in the BJ, ESO-R, R59F, and IIVN
photographic passbands.

Note (2): the bracket indicates an incorrect plate distance estimate
because source is either white dwarf or subdwarf candidate
Note (3): Notes as follows:
a = Common proper motion companion; see Table 5.
b = White dwarf candidate selected from RPM diagram; if white dwarf,
plate distance is incorrect; see Table 4.
c = Not detected during automated search but noticed by eye during
the blinking process.
d = Subdwarf candidate selected from RPM diagram; if subdwarf, plate
distance is incorrect.
e = Source not in 2MASS.

more reliable WD distance estimate in note
g = All colors are too blue or too red for distance relations
h = WD confirmed via spectroscopy; results to be published in a

Note (2): Flags as follows:
a = Distance estimate unreliable when listed (in brackets);
if distance not given, BRI photometry not available
b = Companion not detected during automated search but noticed to
be a CPM companion during visual inspection
c = Fewer than six relations; therefore, distance estimate
unreliable (in parentheses); Hipparcos distance given in notes
when available
d = WD candidate with unreliable distance when listed (in brackets)
e = No 2MASS photometry available for companion
f = I photometry suspect, therefore distance unreliable (in parentheses)
g = Subdwarf candidate with unreliable distance listed (in brackets)
h = Distance estimate unreliable (in parentheses) because primary
is likely a double
