z-band observations of the NOAO Deep Wide-Field Survey Boötes field =================================================================== This product contains the zBootes catalogue: z-band observations of the NOAO Deep Wide-Field Survey Boötes field. These data were released and described in Cool, 2007 (ApJS, 169, 21). That paper should be used as a reference for using any of the data products as several key properties of the images and catalogues are described in that document. The original web site is http://r2.sdm.noao.edu/nsa/zbootes.html There are two versions: - `zBootes_20160711.fits` is the main catalogue.

We used the Sextractor documentation but some units may not be accurate. - `zBootes_MLselected_20160711.fits` is the masterlist selected version of the catalogue. It has been cleaned from duplicates and limited to the HELP field. The help_id column makes the link with the HELP masterlist. Please use this identifier while crossmatching.
