Some of the tilted ring parameters fitted by the routines ROTCUR and KINEMETRY. The top panel shows the term k5, which is a higher order term in the KINEMETRY outputs. In the bottom panel we show the shifts of the systemic velocity, and, in the middle panel, the orbital center shifts along the y-axis in the south-north direction (filled square symbols) and along the x-axis oriented from east-to-west (open square symbols).
