| Abstract: | With the purpose to search for infrared excess objects near the galactic plane, a starfield of 28.5 square degrees in Vela direction has been measured on UK Schtnit plates R 4272 and 1 4183 with the Cosmos machine at Royal Observatory, Edinburgh. The magnitude limit is down to R-20 and I-19, respectively. Star counting and data reduction of the photographic R-I photometry were carried out by the VAX 11/780. 131 infrared excess objects with colour index R-I>2.5 in the field are discovered. Using our position identification criterion, 3 red stellar objects have been identified as optical counterparts of the IRAS point sources. |
