Abstract / Description of output
This paper defines the UKIRT Infrared Deep Sky Survey (UKIDSS) Early
Data Release (EDR). UKIDSS is a set of five large near-infrared surveys
being undertaken with the United Kingdom Infrared Telescope Wide Field
Camera (WFCAM). The programme began in 2005 May and has an expected
duration of 7yr. Each survey uses some or all of the broad-band filter
complement ZYJHK. The EDR is the first public release of data to the
European Southern Observatory (ESO) community. All worldwide releases
occur after a delay of 18 months from the ESO release. The EDR provides
a small sample data set, ~50deg2 (about 1 per cent of the
whole of UKIDSS), that is a lower limit to the expected quality of
future survey data releases. In addition, an EDR+ data set contains all
EDR data plus extra data of similar quality, but for areas not observed
in all of the required filters (amounting to ~220deg2). The
first large data release, DR1, will occur in mid-2006. We provide
details of the observational implementation, the data reduction, the
astrometric and photometric calibration and the quality control
procedures. We summarize the data coverage and quality (seeing,
ellipticity, photometricity, depth) for each survey and give a brief
guide to accessing the images and catalogues from the WFCAM Science
Archive.
