Velocity maps and model fits to the ALMA CO line data of HD 100453. In all images north points up and east to the left. Top left: quadratically collapsed moment map derived with bettermoments. Top center: best-fit Keplerian disk model derived with the eddy tool. Top right: residuals after subtraction of the model from the data. Bottom panels: iso-velocity contours of the best-fit model plotted for the individual channel maps of the data cube.
