Description
Raw observations from a university radio telescope, recorded to tape and never fully analysed.
Provenance
Donated by the creator’s family in 2002. The tape had stretched near its start; the first blocks were repaired by hand from the sampled signal. All files were recovered; 19 damaged sectors were rebuilt from redundant data.
