We solicited responses from all subscribers to the Archive Newsletter, those who had a GALEX CASJobs account, and to all those who had retrieved data from DADS in the previous 28 months. We also placed an invitation to participate in the survey on the MAST web pages.

With questions 1 through 6, we asked questions to characterize MAST usage and to determine the platforms and browsers MAST users are utilizing. The remaining questions attempt to solicit input concerning various tools and services MAST has either implemented or may plan to implement in the future. We provided several places for responders to enter comments and suggestions. We have responded to some of these comments and suggestions on the page We really like to receive questions and comments throughout the year as you discover needs or have questions. Please send suggestions to the archive help desk at or call at 410-338-4547 between 9:00 AM and 5:00 PM eastern time.

The Hubble Legacy Archive (HLA) provides another interface to Hubble data, including enhanced combined images, extracted grism spectra, source lists, and user-contributed products. Through the HLA interface, users can quickly find which HST data have been taken in a given region of the sky, select them through a graphic footprint or tabular interface, and visualize science-grade images and spectra right from their browsers.
