We would like to acknowledge the FUSE project for supplying
much of the web content available from MAST.
The FUSE Project and MAST staff members worked very hard during
the FUSE closeout period to ensure that all data, documentation, and
useful web content was transferred from the FUSE website to MAST.
The FUSE project completely rewrote the FUSE Instrument and Data Handbooks
to be useful for the archival user.
Comments about the FUSE archive or MAST interface should
be sent to
