The Cycle 24 Announcement webpage
provides links to information and documentation that will be useful to you while preparing your proposals. This page will also provide any late-breaking updates on the Phase I process, and answers to frequently asked questions.
The Phase I Proposal Roadmap
is a high level step-by-step guide to writing a Phase I Proposal. Links to the appropriate sections of various documents (Call for Proposals, Primer, etc.) are given for each step.
The HST Primer
provides a basic introduction to the technical aspects of HST and its instruments, and explains how to request the appropriate number of orbits in a Phase I proposal.
The HST Data Archive is part of the Mikulski Archive for Space Telescopes (MAST
). The HST Data Archive contains all the data taken by HST. Completed HST observations from both GO and GTO Programs are available to the community upon the expiration of their proprietary periods. Observations taken under Large and Treasury Programs generally carry no proprietary period.
The MAST HST main page
provides an overview of the HST Data Archive, as well as the procedures for retrieving archival data (see also the introductory description in Section 7.2 of the HST Primer
). The Canadian Astronomy Data Centre
(CADC) and the European Space Agency Centre
(ESAC) maintain copies of the HST science data, and are the preferred sources for Canadian and European astronomers.
The Hubble Legacy Archive (HLA)
is a project to offer enhanced HST archive products. The HLA is a joint project of the Space Telescope Science Institute, the European Coordinating Facility, and the Canadian Astronomy Data Centre. It offers access to high level HST products including composite images and interactive tools for previewing data products. Section 7.3 of the HST Primer
contains more detailed information about the HLA.
The HLA also produces source lists for tens of thousands of HST images. The Hubble Source Catalog (HSC)
combines these visit-based WFC3, ACS, and WFPC2 source lists from the HLA in to a master catalog
with roughly 100 million sources, hence providing entry into the field of database astronomy. Searches that would require months or years to perform in the past can, in may cases, be done in seconds. This resource may be used to support a wide range of new archival proposals, a few potential examples of which are listed in Section 7.4 of the HST Primer
. Version 1 of the HSC was released in February 2015, and Version 2 is scheduled to be released in February 2016.
See Section 5.1 of the HST Primer
for more information on Bright Object Constraints.
