Flying through the XDF in 3-D. Movie credit: hubblesite.org.
The eXtreme Deep Field (XDF) project created the deepest image yet taken of our Universe by combining over a decade of Hubble data in fields surrounding the original Hubble Ultra-Deep Field, resulting in a total integration time of 1.8 million seconds (more than 20 days!) Optical (ACS/WFC) and near-IR (WFC3/IR) images were drizzled down to two different image scales: ACS data at a high-res (30 mas) scale, and both ACS and WFC3 at a low-res (60 mas) scale. Users may download the science images for each filter, and the corresponding weight maps, as FITS files at the MAST XDF page. This page also explains how the XDF was created using past HST data, lists which program IDs went into it, and provides zero-points for converting the fluxes from electrons/second to AB magnitudes.
