Data

XDF Data Release 1.0

The data used to generate the XDF were taken over the decade from mid-2002 to the end of 2012. The total exposure on the XDF is about 1.8 million seconds using data from Hubble's two main workhorse cameras, the Advanced Camera for Surveys Wide Field Channel (ACS/WFC) and the Wide Field Camera 3 InfraRed Channel (WFC3/IR). Substantial gains accrue from using all the ACS data taken over the decade since 2002, as well as from the improved processing techniques since the HUDF was released. The gains in the XDF are equivalent to adding about 180 orbits of data to the original HUDF dataset — split roughly equally between gains from improved processing techniques and from new data.

Further background on the XDF, including how and why this project was initiated, can be found at http://xdf.ucolick.org/xdf.html. The generation of the processed, combined and aligned images for the XDF was carried out over the last year by XDF team members Dan Magee, Pascal Oesch, Rychard Bouwens and Garth Illingworth (see Illingworth et al 2013). The XDF team can be found at http://xdf.ucolick.org/team.html. The data products for XDF have been release as a HST High Level Science Product and can be downloaded here.

HUDF09 Data Release 1.0

The Hubble Ultra Deep Field 2009 (HUDF09) program observations obtained by HST program 11563 (PI: Garth Illingworth) in Cycle 17 has made publicly available. The program uses WFC3/IR as the prime instrument for 192 orbits to image the deep ACS fields that were obtained in the original HUDF (PI: Steven Beckwith) program and in the HUDF05 (PI: Massimo Stiavelli) program. We have released the data products for this program as an HST High Level Science Product and can be downloaded here.

GOODS NICMOS Archival Data

As a part of a HST Archival Research proposal (10937) titled Probing the Galaxy Population at z~7-10 Using Archival ACS & NICMOS data Rychard Bouwens and I retrieved and process nearly all NICMOS camera 3 F110W and F160W data taken over the GOODS North and South fields. The data products for this dataset have been release as a HST High Level Science Product and can be downloaded here.
