By employing a quantitative measurement of morphometric indicators with the algorithm MORFOMETRYKA on Hubble Space Telescope (F606W) images of the galaxies, we present a novel morphology-based method for determining trail vectors. We study the surface brightness profiles and curvature of the candidates and compare the results obtained with two analysis packages, MORFOMETRYKA and IRAF/ELLIPSE on retrieving information of the irregular structures present in the galaxies. Our morphometric analysis shows that the ram-pressure stripping candidates have peculiar concave regions in their surface brightness profiles. Therefore, these profiles are less concentrated (lower Sérsic indices) than other star-forming galaxies that do not show morphological features of ram-pressure stripping. In combination with morphometric trail vectors, this feature could both help identify galaxies undergoing ram-pressure stripping and reveal spatial variations in the star formation rate.engAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Galaxies: clusters: intracluster mediumGalaxies: evolutionGalaxies: irregularinfo:eu-repo/semantics/article10.1093/mnras/staa32261365-2966info:eu-repo/semantics/openAccess
