Data Release

A preliminary data release of CATS adaptive optics (AO) observations of over 300 galaxies are now available. These images are primarily in fields with existing multi-wavelength data from HST, Spitzer, and Chandra. These observations were obtained with the Keck Natural Guide Star (NGS) AO facility, and focused on the GEMS and COSMOS galaxy fields. Please contact either James Larkin, David Koo, or Claire Max for the username and password.

Access CATS Data Release



In this data release, we are providing basic information on all of the CATS observations. Reduced Fits images of the NGS observations are available for download. We are also providing one data set in raw form for researchers to examine. Finally we are providing a library of NGS point-spread-functions (PSFs) to help constrain photometry.
