Within these regions we detect 15 compact radio sources which we identify as radio protostars including two probable new detections. The sample is in general of low bolometric luminosity and contains several of the newly detected VeLLO sources. We determine the 1.8cm radio luminosity to bolometric luminosity correlation, Lrad-Lbol, for the sample and discuss the nature of the radio emission in terms of the available sources of ionized gas. We also investigate the Lrad-LIR correlation and suggest that radio flux density may be used as a proxy for the internal luminosity of low-luminosity protostars. Description: Radio flux densities at a wavelength of 1.8cm for 46 sources within small clouds and cores from the Spitzer c2d programme are presented. These are interferometric observations with a resolution of approximately 25-arcsec. All sources are detected at greater than 5σ unless otherwise noted. File Summary:
