...…is placed on the ABν system using three fundamental standards (BD + 17◦4708, BD + 26◦2606, and BD + 21◦609), whose magnitude scale is as defined by Fukugita et al. (1996); a set of 157 primary standards, which are calibrated by the above fundamental standards using the USNO 1m telescope, and…...

...The five filters in the imaging array of the camera, [u′, g′, r′, i′ and z′] have effective wavelengths of [3590 Å, 4810 Å, 6230 Å, 7640 Å and 9060 Å] (Fukugita et al. 1996; Gunn et al. 1998)....

...Comparison with positions from the FIRST (Becker et al. 1995) and 2MASS (Skrutskie 1999) catalogues shows that the rms astrometric accuracy is currently better than 150 milliarcseconds (mas) in each coordinate....

...The atlas images are sized to enclose the area occupied by each object plus the PSF width, or the object size given in the ROSAT or FIRST catalogues....

...The photometric data products of the SDSS include: a catalog of all detected objects, with measured positions, magnitudes, shape parameters, model fits and processing flags; atlas images (i.e. cutouts from the imaging data in all five bands) of all detected objects and of objects from the FIRST and ROSAT catalogs; a 4× 4 binned image of the corrected images with the objects removed: and a mask of the areas of sky not processed (because of saturated stars, for example) and of corrected pixels (e.g. those from which cosmic rays were removed)....
