FURTHER DISCUSSION OF BINARY STAR RADIO SURVEY DATA

Statistical information on 8280 individual radio observations of binar y stars, predominantly at 8.4 GHz using the Parkes 64 m antenna, is pr esented. Three main groups are distinguished: (i) RS CVn stars, (ii) c lassical Algol binaries (EA2s), and (iii) detached pairs of generally early type (ETBs). The RS CVn stars more frequently gave rise to detec table fluxes, while the ETBs, in these data, are a small and rather he terogeneous class. The Algols' emission appears to increase near conju nction phases, though Ne cannot clearly distinguish any special proper ty of the Algols' phase-dependent behaviour that is not also shared by the RS CVn binaries. Both these categories' data show a bimodal, phas e-dependent pattern to the distribution of detections, suggesting that these binary types share similar underlying physical properties, thou gh there could also be other factors at play. The sample sizes of the Algols and particularly the ETB detections are too small for effective , discriminatory statistics, however.
