Info on MAST Web Site
The MAST web site is basically organized by mission, with each mission having it's own home page. For active missions which maintain their own web site (e.g., FUSE, TUES, & GSC), links are made directly to the project-supported pages when appropriate. Also, for some missions (e.g., EUVE ), all or part of the data archive actually resides at another data center but data can be retrieved transparently using MAST-style search forms.
The MAST home page itself contains general information and links to cross-mission tools, software, documentation, and "high-level" prepared datasets. Besides the various cross-mission search tools, seach forms are also available for each individual mission.
