Query: A 1500 deg$^2$ Near Infrared Proper Motion Catalogue from the UKIDSS
  Large Area Survey   The UKIDSS Large Area Survey (LAS) began in 2005, with the start of the
UKIDSS program as a 7 year effort to survey roughly 4000 deg$^2$ at high
galactic latitudes in Y, J, H and K bands. The survey also included a
significant quantity of 2-epoch J band observations, with an epoch baseline
greater than 2 years to calculate proper motions. We present a near infrared
proper motion catalogue for the 1500 deg$^2$ of the 2 epoch LAS data, which
includes 135,625 stellar sources and a further 88,324 with ambiguous
morphological classifications, all with motions detected above the 5$\sigma$
level. We developed a custom proper motion pipeline which we describe here. Our
catalogue agrees well with the proper motion data supplied for a 300 deg$^2$
subset in the current WFCAM Science Archive (WSA) tenth data release (DR10)
catalogue, and in various optical catalogues, but it benefits from a larger
matching radius and hence a larger upper proper motion detection limit. We
provide absolute proper motions, using LAS galaxies for the relative to
absolute correction. By using local 2nd order polynomial transformations, as
opposed to linear transformations in the WSA, we correct better for any local
distortions in the focal plane, not including the radial distortion that is
removed by the UKIDSS pipeline. We present the results of proper motion
searches for new brown dwarfs and white dwarfs. We discuss 41 sources in the
WSA DR10 overlap with our catalogue with proper motions $>$300 $mas yr^{-1}$,
several of which are new detections. We present 15 new candidate ultra-cool
dwarf binary systems.
