NASA Data Center Annual Program Plan
Overall Mission: MAST supports both active and legacy mission data sets, focusing primarily on data in the ultraviolet, optical, and near-IR parts of the spectrum. Support includes curation of the data, providing expert support to users of the data, providing access to data-specific calibration and analysis software, providing user support for this software, and maintaining public access interfaces to the data. MAST works with new mission teams in the supported wavelength regions to assist in the development of data management plans, especially in the areas of data formats, descriptive metadata and standardization of keywords, and in the development of data access and data delivery plans.
MAST Data Holdings
Services Provided: MAST provides support for users seeking to understand the properties and instrumental signatures of all archived data sets and assistance with the interfaces to browse and retrieve these data. Access to non-HST mission and instrument specific calibration and analysis software, and assistance in its use, is on a best-effort basis (full support for HST related software is provided by the MAST Helpdesk and staff).
Non-HST Data Analysis Software Provided: IUE RDAF package (IDL-based), IUE Final Archive processing software (IRAF port), EUVE analysis software package (IRAF-based), Copernicus data analysis software (IDL-based), UIT data reduction and analysis software (FORTRAN, C, and IDL routines), WUPPE data analysis software (FORTRAN routines requiring the FITSIO library), and HUT data reduction software (IRAF-based). IDL software for analyzing IMAPS images will also be made available in the near future.
Mission Interfaces: Ingest of FUSE mission data began in July 1999. Contacts have been established with the GALEX MIDEX mission team, the Sloan Digital Sky Survey, and the CHIPS UNEX mission team. MAST staff have developed working relationships with staff from all three of the instrument teams from the ORFEUS Project and with members of the Voyager UVS team.
Interoperability Activities: MAST and STScI staff have worked on development and testing of the Astrobrowse prototype "Starcast". The MAST web site has search pages and direct links to data retrievals at other astrophysics data centers (EUVE, ROSAT, and ASCA at HEASARC) and provides an interface that enables other sites to send queries to the MAST database. MAST collaborates with the ADS to provide links to published papers referencing specific data sets and links from the ADS abstracts to the archived data. MAST staff also serve on the Astrophysics Data Center Coordinating Council.
Major Activities and Accomplishments of the Past Year:
MAST began the public distribution of data from its automated CD jukebox system in October 1999. Staff members completed the migration of data acquired from GSFC (ADF, NSSDC, and LASP) onto CD-ROMs, including IUE Final Archive data, IUESIPS, ASTRO-UIT, ASTRO-HUT, ASTRO-WUPPE, and Copernicus. The data were verified and where necessary FITS formats were corrected. Data from IMAPS and BEFS instruments from the first ORFEUS mission were obtained and integrated into the archive.
MAST has maintained and enhanced its web site for all the missions it supports. Each mission's web interface provides the capabilities to search the database, preview the data, and retrieve selected data, as well as access to available documentation and software. Preview data for IUE and UIT were obtained from the ADF and adapted for the MAST website. Preview data for the HUT, BEFS, and EUVE missions were created and made publicly available.
With the launch of FUSE in September 1999, MAST began archiving FUSE data and distributing copies to the guaranteed observers and guest observers. In February 2000, the first public FUSE data were made available. Staff members worked with software specialists and FUSE team members to smoothly integrate FUSE archive activities and support into the existing HST DADS system. This approach provides reliable, cost-effective archival support to researchers through a familiar interface.
MAST staff have implemented a system of links between MAST datasets and publications in the scientific literature. The links, provided in cooperation with the ADS, allow researchers to access the published abstracts and articles resulting from analyses of our datasets, and vice versa. All IUE links are currently up to date. Links between HST programs and their resulting publications are complete from 1990 through 1995 and for all of 2000. Links to the information for the remaining HST programs and the other supported MAST missions are expected to be completed in the near future. (The HST literature effort is funded separately).
MAST staff completed a number of smaller projects which provide enhanced support to archival researchers.
