Here, we provide access to the optical
imaging obtained for zBootes, a z-band survey of the NOAO Deep
Wide-Field Survey Bootes Field using the Steward 2.3m Bok telescope and
the 90Prime imager. 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 catalogs are described in that document.
The zBootes imaging covers 7.62 of the NDWFS survey area and reaches a
mean 50% completeness limit of 22.8 mag in the z-band.
The final zBootes catalog consists of more than 200,000 objects.
With these depths, our images should be sensitive to L* galaxies
out to a redshift of about 1. These data have many possible
applications includinng searching for and characterizing high-redshift
quasars and brown dwards. Also, these photometric measurements
provide added constraints to photometric redshift deteminations of
galaxies and active galaxites to moderate redshifts and will add to the
existing wealth of multi-wavelenght observations available in the NDWFS
The data can be obtained using the links below:
-- the final 72MB merged catalog of all of the zBootes object detections. Each object is listed in this catalog once. If an object was observed multiple times, only the best observation is included in this catalog.
-- The zBootes images and weight maps are available through the NOAO Science Archive.
-- Catalogs for each individual zBootes field as well as the final merged catalog of all of the zBootes object detections.
