Abstract
A sample of 57 sources from the Ooty Lunar Occultation survey at 327 MHz has been studied using the 3-element interferometer system at Green Bank at frequencies 2.7 and 8.1 GHz. A comparison of the angular separation at low and high frequencies for well resolved double sources does not show any frequency-dependent effects. The mean spectral index of the 42 doubles in the sample is 0.92, considerably steeper than the usual mixed samples. The source 1417-19 is found to be a triple source, with a strong central component coinciding with the N galaxy suggested as the identification.
