3.2 The APT Visual Target Tuner (VTT) and Aladin

The Visual Target Tuner (VTT), within the Astronomer's Proposal Tool (APT), has been replaced by a new tool based on the Aladin Sky Atlas Interface. This change gives us more 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 more capabilities for displaying and manipulating images. Detailed information about the new Aladin based tool can be found on the APT Web page:
