However, the depth in the area outside the blue diamond is quite limited and so it is not included in the XDF submission. The XDF ACS image is the sum of ALL the ACS data that overlaps, partially and fully, with the blue outlined area (including CANDELS and Supernova search fields, etc.) To ensure that the edges of the XDF field were dealt with adequately, and that the alignment was performed correctly, even to the edges, all the ACS image data within the black square was aligned and co-added. The XDF excludes the some less-deep data around the very edges of the HUDF. The XDF 'blue diamond' is just inside the footprint of the original Hubble Ultra-Deep Field (HUDF) (PI: Steven Beckwith). The figure shows all the data that was used to generate the XDF. 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 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.įurther background on the XDF, including how and why this project was initiated, can be found at. 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 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). The data used to generate the XDF were taken over the decade from mid-2002 to the end of 2012. The weight maps are appropriately adjusted for the partial coverage. The XDF also includes images which only partially cover the HUDF, as shown in the figure below. Small amounts of data taken with unusual or rarely used filters and spectroscopic data are not included. The XDF includes all optical and infrared data taken by Hubble covering the original Hubble Ultra-Deep Field (HUDF) program, with just a few exceptions.

This summary describes the Hubble eXtreme Deep Field (XDF) project data release.
