Figure 6: (a) Distribution of radio luminosity, , with bolometric luminosity, , for YSOs (figure reproduced from [164]); (b) distribution of radio detected YSOs as a function of bolometric luminosity, compared to the expected distribution of YSOs from Dunham and Vorobyov [165]. Grey hatching indicates objects from the combined catalogues of Anglada [143], Furuya et al. [188], and Scaife et al. [151153]. Red hatching indicates the objects detected at 16 GHz [151153].
