Astronomer's Proposal Tool

The Astronomer's Proposal Tool (APT) is software that can be used to submit Phase I/DD proposals and Phase II proposals for the Hubble Space Telescope. 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 via StarView.

The APT installers and documentation are available on the left hand side of this page. "Training Materials" is a compact table of contents of all APT documents. The "Roadmaps" are step-by-step guides to the proposal process with links to both proposal and APT documentation.
