AbstractWe compare the all-sky AKARI/Far-Infrared Surveyor (FIS) Bright Source Catalogue (BSC) Version 2 with the Herschel/ Photodetector Array Camera and Spectrometer (PACS) Point Source Catalogue (PSC), in order to investigate condition for correct matching. We define a ''fake''-match rate based on the AKARI-Herschel flux ratio and study the dependence of this rate on the source density of the region (Ndens), AKARI-Herschel separation (D), Galactic latitude (absolute value of b), and the AKARI flux. We find that the 'fake'-match rate depends on Ndens, D, and absolute value of b and not strongly on the AKARI flux where the sources with smaller Ndens and D and larger absolute value of b result in lower ''fake''-match rate. In our analysis, if we limit the AKARI sources with FQUAL= 3, Ndens = 0 and absolute value of b greater than 30 degrees, and adopt a searching radius of less than 10 arcsec, the source is likely to be matched with an appropriate counterpart in a catalogue of astronomical data whose position accuracy is better than that of the AKARI catalogue.
