Scientific paper

An OSRT (Ooty Synthesis Radio Telescope) map of a 2°×1° field around Sco X-1 with resolution of 3×3 arcmin2 at 327 MHz is presented. There is no evidence of any extended emission around Sco X-1 brighter than 50 mJy beam-1. Two sources in the field, 1617-153 and 1616-160, lie at distances of 15 and 31 arcmin from Sco X-1 and are collinear with its triple source structure. High-resolution (100×50 arcsec2) OSRT maps of these and Sco X-1 are presented. The spectra of the NE and central components in Sco X-1 show low-frequency turnovers around 1 GHz, while the SW components have a power-law non-thermal spectrum.
