cds-question@unistra.frgalaxiesh-i-line-emissiongalaxy-classification-systemsLopsidedness of the gaseous disc of spiral galaxies is a common phenomenon in disc morphology, profile and kinematics. Simultaneously, the asymmetry of a galaxy's stellar disc, in combination with other morphological parameters, has seen extensive use as an indication of recent merger or interaction in galaxy samples. Quantified morphology of stellar spiral discs is one avenue to determine the merger rate over much of the age of the Universe. In this paper, we measure the quantitative morphology parameters for the HI column density maps from the Westerbork observations of neutral Hydrogen in Irregular and SPiral galaxies (WHISP). These are Concentration, Asymmetry, Smoothness, Gini, M20 and one addition of our own, the Gini parameter of the second-order moment (GM). Our aim is to determine if lopsided or interacting discs can be identified with these parameters. Our sample of 141 HI maps have all previous classifications on their lopsidedness and interaction.2011MNRAS.416.2415Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/416/2415CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/136/2563 : HI Nearby Galaxy Survey, THINGS (Walter+, 2008)J/A+A/442/137 : HI observations of WHISP disk galaxies (Noordermeer+, 2005)J/MNRAS/416/2401 : Quantified H I morphology.
