Wide-Field Galaxy and Cluster Surveys Using Cosmos

We have recently completed a catalogue of ∼ 5 million galaxies in the Southern sky down to a limit of b j = 20.5. The catalogue is based on the ROE/NRL Southern Sky Object Catalogue (Yentis et al. 1992), which is the result of processing of scans made with the COSMOS machine at the Royal Observatory Edinburgh (ROE) on glass copies of the IIIa-J survey carried out with the UK Schmidt Telescope (UKST) in Australia. The ‘COSMOS/UKST Southern Sky Galaxy Catalogue’ is based on 500 fields with |b| > 25 degrees and outwith the Magellanic Clouds.
