Progress Report on a Search for Parallax Stars in the Region of the South Galactic Cap

Extract

A series of plates is being taken with the U.K. 48-inch Schmidt Telescope at Siding Spring on a field centred on the star GC 1110 near the South Galactic Pole, in order to detect any stars brighter than about m_pg = 18, which may have significant trigonometric parallaxes.

A search list of more than 16, 300 objects in an area 4¼° × 4¼° has been formed from a preliminary scan on the Galaxy machine at R.G.O. Prom 1974 January to 1976 January some 30 plates have been obtained, nearly half of which have been measured in each of two orientations on Galaxy; each measuring run takes about 16 hours.
