NIR proper motion catalogue from UKIDSS-LAS
Listed in IVOA Registry (Virtual Observatory)
The United Kingdom Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) began in 2005, with the start of the UKIDSS programme as a 7 year effort to survey roughly 4000deg^2^ at high Galactic latitudes in Y, J, H and K bands.
Description
The survey also included a significant quantity of two 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 1500deg^2^ of the two epoch LAS data, which includes 135625 stellar sources and a further 88324 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 300deg^2^ subset in the current Wide Field Camera Science Archive (WSA) 10th 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 second-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 >300mas/yr, several of which are new detections.
We present 15 new candidate ultracool dwarf binary systems.
