These three pictures show a section of the digitized all sky-survey at different compression factors. The images will be written into CDROM (Compact Disk Read-Only Memory) format and will be available to professional and amateur astronomers. The sample image is of a 11.3 arc minute square region of the Hydra cluster of galaxies (Abell 1060), show in the spiral galaxy NGC 3312, and the elliptical galaxies NGC 3312 (right) and NGC 3309 (left).
The top image was digitized from a SRC southern sky survey plate. The image 400 pixels picture elements on a side. The center picture has been compressed by a ratio of 10:1 and is useful for a wide range of astronomical research applications.
The bottom picture shows the data at a compression ratio of 100:1. Though the image is somewhat coarser it is still useful for producing astronomical finding charts. Note also that the morphology of the bright galaxies is still distinguishable. At this high compression, the entire sky survey will fit onto only ten CDROMS.
