3.2 APT and Aladin
The Astronomer’s Proposal Tool (APT) is used to design HST observations. A new tool based on the Aladin Sky Atlas Interface is available to visually inspect fields and objects. This tool gives us many options for future enhancements, and brings a variety of benefits to users including access to a wide variety of images and catalogs, as well as many capabilities for displaying and manipulating images. Detailed information about the Aladin based tool can be found on the APT Web page:
