The Hubble Legacy Fields (HLF-GOODS-S) V1.5 Data Products: Combining 2442 Orbits of GOODS-S/CDF-S Region ACS and WFC3/IR Images
!1 The Hubble Legacy Fields (HLF-GOODS-S) v1.5 Data Products: Combining 2442 Orbits of GOODS-S/CDF-S Region ACS and WFC3/IR Images. Garth Illingworth1, Daniel Magee1, Rychard Bouwens2, Pascal Oesch3, Ivo Labbe2, Pieter van Dokkum3, Katherine Whitaker4, Bradford Holden1, Marijn Franx2, and Valentino Gonzalez5 Abstract We have submitted to MAST the 1.5 version data release of the Hubble Legacy Fields (HLF) project covering a 25 x 25 arcmin area over the GOODS-S (ECDF-S) region from the HST archival program AR-13252. The release combines exposures from Hubble's two main cameras, the Advanced Camera for Surveys (ACS/WFC) and the Wide Field Camera 3 (WFC3/IR), taken over more than a decade between mid-2002 to the end of 2016. The HLF includes essentially all optical (ACS/WFC F435W, F606W, F775W, F814W and F850LP filters) and infrared (WFC3/ IR F098M, F105W, F125W, F140W and F160W filters) data taken by Hubble over the original CDF-S region including the GOODS-S, ERS, CANDELS and many other programs (31 in total). The data has been released at https://archive.stsci.edu/prepds/hlf/ as images with a common astrometric reference frame, with corresponding inverse variance weight maps. We provide one image per filter of WFC3/IR images at 60 mas per pixel resolution and two ACS/WFC images per filter, at both 30 and 60 mas per pixel. Since this comprehensive dataset combines data from 31 programs on the GOODS-S/CDF-S, the AR proposal identified the MAST products by the global name "Hubble Legacy Field”, with this region being identified by “HLF-GOODS-S”.

The Hubble Space Telescope …. and it’s successor …. plus ‘Edwin Hubble, his life and work’ Context - what and where • Solar system • Distances • Stars and Galaxies • The Milky Way • Earliest Light The Solar System The Solar system formed about 5 billion (5 thousand million) years ago. The circumference of Earth is 40,000km (25,000 miles) and of the Moon is 11,000 km (6,800 miles). We are, on average, 93 million miles (150 million kms) from the Sun, and it takes 8 minutes 20 seconds for light from the Sun to reach the Earth. The average distance from the Earth to the Sun is also known as one Astronomical Unit (AU). Astronomical units are usually used to measure distances within our Solar System. The Earth orbits the Sun in one year. One day is the time it takes for the earth to spin round once. Other planets orbit at different rates; eg, Jupiter takes 12 years for one orbit of the Sun; Mars takes 687 days. The Moon orbits around the Earth once every 27.32 days. It is 250 thousand miles (400 thousand km) away, so it takes 1.3 seconds for light to travel from the Moon to us. Every individual star your eyes can see in the night sky is in the Milky Way Galaxy. Our Sun is just one minor star in one Galaxy Distances and times Distances in space are so huge that new measurements are needed. The distance measurement often used is the light-year, the distance that light travels in one year in a vacuum.

The purpose of this article is to refl ect a little on what Hubble has already achieved and, rather more importantly, to remind ourselves what still needs to be done to ensure that the full legacy of this great project can be properly realised.

Calibration Status and Results for Wide Field Camera 3
The 2005 HST Calibration Workshop Space Telescope Science Institute, 2005 A. M. Koekemoer, P. Goudfrooij, and L. L. Dressel, eds. Calibration Status and Results for Wide Field Camera 3 Randy A. Kimble NASA, Goddard Space Flight Center, Greenbelt, MD 20771 and the WFC3 Team Abstract. Wide Field Camera 3 (WFC3) is a general-purpose imager in develop- ment for installation in HST Servicing Mission 4 (SM4). Covering the wavelength range of 200-1700 nm in two observing channels, WFC3 offers powerful new capabil- ities, particularly in the near-ultraviolet and near-infrared bands. During 2004, the instrument was integrated and underwent a substantial suite of end-to-end charac- terization and performance tests. In this paper, we present a brief overview of the design and scientific purpose of WFC3, summarize the results of its test program to date, and highlight some recent developments in detector technology that will further enhance the performance of WFC3’s IR channel. 1. Design and Purpose of WFC3 The WFC3 program originated in 1997 when NASA decided that the target date for the end of the HST mission would be moved from 2005 to 2010. Recognizing that this date would place HST’s complement of imagers beyond their nominal design lifetimes, the HST Project initiated the development of a new camera to ensure and extend HST’s imaging capabilities into those later years. WFC3 was thus conceived, to be developed as a facility instrument on behalf of the astronomical community (that is, with no PI team and no Guaranteed Time Observations). Day-to-day scientific guidance is provided by a Science Integrated Product Team from NASA/GSFC and STScI, with broad guidance exercised by a community-based Science Oversight Committee, chaired by R.

SOURCE of ATOMIC HYDROGEN in the ATMOSPHERE of HD 209458B Mao-Chang Liang,1 Christopher D
The Astrophysical Journal, 596:L247–L250, 2003 October 20 ᭧ 2003. The American Astronomical Society. All rights reserved. Printed in U.S.A. SOURCE OF ATOMIC HYDROGEN IN THE ATMOSPHERE OF HD 209458b Mao-Chang Liang,1 Christopher D. Parkinson,1 Anthony Y.-T. Lee,1 Yuk L. Yung,1 and Sara Seager2 Received 2003 June 27; accepted 2003 August 28; published 2003 September 18 ABSTRACT Atomic hydrogen loss at the top of HD 209458b’s atmosphere has been recently suggested (Vidal-Madjar et al.). We have developed a one-dimensional model to study the chemistry in the upper atmosphere of this extrasolar “hot Jupiter.” The three most abundant elements (other than He) as well as four parent molecules are included ∼ in this model, viz., H, C, O, H2, CO, H2O, and CH4. The higher temperatures ( 1000 K) and higher stellar irradiance (∼6 # 10 5 W mϪ2 ) strongly enhance and modify the chemical reaction rates in this atmosphere. The main result is that the production of atomic hydrogen in the atmosphere is mainly driven by H2O photolysis, and the reaction of OH with H2, and is insensitive to the exact abundances of CO, H2O, and CH4. For comparison, the bulk H concentration for “hot Jupiters” is 3 orders of magnitude higher than that of Jupiter. Subject headings: planetary systems — radiative transfer — stars: atmospheres — stars: individual (HD 209458) 1. INTRODUCTION 2. MODEL Since the discovery of the ﬁrst extrasolar planet, 51 Peg b, Our model is based on the four parent molecules H2, CO, in 1995 (Mayor & Queloz 1995), a total of 102 planets have H2O, and CH4 and is a derivative of the Caltech/JPL kinetics so far been discovered (e.g., Butler et al.
