WIRDS Terapix T0001 Release

Data Download Access

The WIRCam Deep Survey (WIRDS) is a CFHT Large Program which was carried out using WIRCam at the CFHT between semesters 06A and 08B. WIRDS provides broad-band near-infrared data for the CFHTLS Deep Fields.

The present release comprises WIRDS data in the J, H and Ks filters for the D1 field (022559-042940). WIRCam has a pixel scale of 0.3 arcsec/pixel and the data are acquired with half-pixel micro-dithering to improve the spatial resolution. The released images have been re-sampled to the MegaCam pixel scale of 0.186 arcsec/pixel so that each pixel in the WIRDS images is matched to the equivalent location in the optical CFHTLS T0005 images. Note that due to the smaller field of view of WIRCam, only part of the optical field is covered in the near-IR.

Details on how the stacks were constructed, quality assessment information and a description of meanings of file names are provided on the Terapix WIRDS-D1 data description page. There is a README file which also provides information on the available images and catalogues.
