Fig. 5
Histogram of the VLBA detections and non-detections, binned in the compactness at 1.4 GHz. Compactness is defined as the ratio of mas-scale flux density to arcsec-scale flux density. The vertical lines show the mean compactness – from left to right – of all VLBA-undetected IFRS, of all VLBA-observed IFRS, and of all VLBA-detected IFRS, respectively. The former two lines represent upper limits as indicated by the horizontal arrows.
