The Observatory Science Group (OSG) lies within the Science Support Division
(SSD) at the Space Telescope Science
Institute, and provides general support of HST as a productive observatory. This domain
currently involves three main responsibilites:
- Maintaining calibration parameters and throughput data for HST and its
Science Instruments.
- Supporting science through focal plane calibrations, SI aperture
position determinations, and analysis of telescope pointing.
- Monitoring focus variations and dependencies.
Further related duties include the Data Quality Coordinating Committee, an
initiative to increase the scientific productivity of HST users by improving
the data assessment, processing, calibration, and archiving functions.
