Clickable image map
(All 10-sigma objects are clickable. Segments are overlaid on color ACS & NIC3 images.
BPZ redshifts, SED fits, and P(z) given for each galaxy.)



Objects with "confident" spectroscopic redshifts.
"Best" z > 6 candidates

Tarballs of all ACS and NIC3 color images.


Definition of objects and their extents / apertures used for photometry:

Obtain photometry on the objects as defined in the segmentation map by using:


Automatically obtain aperture-matched PSF-corrected photometry across filters with:
(Available now!)
ColorPro

BPZ is now packaged with ColorPro!
After producing the final photometric catalog, ColorPro will automatically run BPZ for you if you wish, with any options you included in the ColorPro configuration file.


Obtain Bayesian Photometric Redshifts of the galaxies using Narciso Benítez's BPZ:
