Comparison of BeeP’s Free flux densities at 857 GHz with aperture flux-density values (APERFLUX) from PCCS2+2E. We plot ln(S_BeeP/S_APERFLUX) against APERFLUX (left) and SRCSIG (right). Upper row: distribution of the PCCS2 values in blue (contours are [68, 95, 99]%). The red dots are sources that moved by more than one pixel from the original PCCS2+2E position. Lower row: full PCCS2+2E. The red contours represent the distribution of sources that moved by more than one pixel, and the blue ones the remaining population. Top row: we show individual dots because there are too few of them to make a density plot.
