Scientific paper
From the twenty CCD observations made with the Schmidt telescope of Beijing Observatory, the optical positions of four radio sources 0851+202, 1228+126, 1442+101 and 1749+701 are given, using the method of single plate-constant and taking five catalogues as references: ACT, CMC, PPM, NPM and HIP. A comparison between the results and those of other authors is also made.
