MORFOMETRYKA output for CAVITY 52731 (upper row), CAVITY 52732 (middle), and CAVITY 52733 (lower). In the columns, from left to right: original image in g band (arcsinh scale); single Sérsic model fit and PSF (lower left insert); single Sérsic residual; asymmetry map; and brightness profile (black dots) and 1D (yellow) and 2D (red) derived Sérsic models. In the leftmost panels, the dark green line is the initial segmentation region; the neon green lines are the two Petrosian radius regions (obtained both by fitting Sérsic and by image momenta); the red line corresponds to the Sérsic R_n. In the rightmost panels, black dots and bars are measurements and associated uncertainties; the yellow line is the Sérsic fit to the 1D profile; the red line is the profile but with the parameters obtained from the image (2D) fits.
