Astronomers Proposal Tool (APT) for HST


The Astronomer's Proposal Tool (APT) is used to write, validate and submit proposals for the Hubble Space Telescope. (It will also be used eventually for James Webb Space Telescope proposals.) APT is an integrated toolset consisting of editors for filling out proposal information, an Orbit Planner for determining feasibility in Phase II, a Visit Planner for determining schedulability, diagnostic and reporting tools, a Bright Object Tool for performing bright object checks, and an integrated tool based on Aladin for viewing exposure specifications overlaid on FITS images and querying the HST Archive.
