Flux errors are estimated from the difference between the fluxes from the A and the B images. In the top, middle, and bottom panels, flux errors in N3, S9W, and L15 are shown. Red points indicate the difference multiplied by . Green crosses indicate the median value in a log flux bin size of 0.08. The blue dotted line shows the fitting result. The higher value of the red point and the line was adopted as the flux error.
