HEASARC services

The HEASARC provides a number of services and has capabities to facilitate the archive of mission data or high level products results of a scientific investigation. The list below may be customed to account the mission needs: Provide and maintain the archive infrastructure for any mission data or data products. Archive the mission data for all mission phases: pre-launch, during mission operation and after operations ended. Design the archive structure for science and housekeeping for all mission data. The mission archive includes the data sets Design and Ingest the mission database tables in the HEASARC database system. Database tables are used to browse the data. Give public access to the mission data via the HEASARC on-line system which includes HTTPS and FTPS protocols.

The data are encrypted during this period. Provide and maintain the HEAsoft software infrastructure, environment and repository. Maintain and update all the mission independent tools and the FITS manipulation tools. Ingest the mission software package in HEAsoft and distribute the software. Provide and maintain the data transfer protocol software (ex. Data Transfer System). Archive , distribute and provide software access to the mission calibration data. Provide expertise for the mission science and calibration FITS files design. The design accounts for : re-use of file structure and interoperability with other missions , re-use of the existing software, implement FITS and OGIP standards. Provide, maintain and update the ARK/RPS system, in preparation for guest observer proposal submission. Provide a Web server, standard settings for the mission Web pages and maintain the Web pages with the data archive and calibration. Scientific expertise in the use of the mission archive.
