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. The data are organized into sets of images by HUDF09 pointing and by passband (WFC3/IR F105W, F125W & F160W). Each image is approximately 3k x 3k pixels in size and a scale of 0.06 arcsec/pixel. All three pointings reside in the GOODS/Chandra South field and each pointing includes a drizzled science image and a weight image. http://archive.stsci.edu/prepds/hudf09/ Archive Research 2 http://archive.stsci.edu/siap/search.php?id=hudf09& GET Pointed 360.0 360.0 360.0 360.0 0 0 44426720 18 HST ACS WFC3 Infrared
