Abstract:
We present details of the second part of the Southern Infrared Proper
Motion Survey (SIPS). Here accurate relative astrometry allows us to
reduce the minimum proper motion to 0.1"/yr. This yields 6904 objects
with proper motions between our minimum cut and half an arcsecond a
year. A small overspill sample with proper motions greater than this
is also included. We examine our sample to identify interesting
individual objects such as common proper motion binaries, potential L
dwarfs and candidate nearby stars. Finally we show our survey is
incomplete due to many factors, factors which we will take into
account when simulating these survey results in the next paper in this
series.
