Example of the GPv2 verification output for galaxy LEDA 2308331. The coordinates of the center (x0, y0) have been fixed while b/a and PA have been left variable. Blue dots indicate the parameters of individual fitted ellipses. The magenta line marks the adopted size of the galaxy, showing the median value of the different parameters and the points that were included in the median calculation. The light-blue vertical lines show the error bars. In this figure, the ellipticity values show that the outer region of the galaxy behaves differently than the inner one. The magenta line illustrates that the adopted size of the galaxy is slightly larger than the limit where the noise starts to dominate the isophots.
