1. All data generated by HST are preserved in a specially-designed interim archive system, the “Data Management Facility” at ST ScI.
2. Data is currently being written to 2 Gb – 12” optical disks at the rate of about 0.5 Gb/day = 35 exposures/day.
3. A catalog is produced as the data is archived. This catalog is publically accessible and currently contains information on over 19,000 exposures (images, spectra, flat fields, calibration data, etc.)
4. About 14,000 exposures are now non-proprietary; more than a third of these are observations of sky targets obtained during OV/SV.
