Sky maps of Rf for CO(10) (upper panels) and CO(21) (lower panels) observations. Units are Jy beam-1 km s-1 arcsec. From left to right: all velocities, | Vx | < 2 km s-1 and | Vx | > 2 km s-1. The circles at R = 3.5′′ correspond to the enhancement seen by Winters et al. (2007) in the narrow velocity component of the CO(21) data. The projection of the star axis on the sky plane (making an angle of 13° with the line of sight) and the axis from which the stellar longitude ω is measured (positive clockwise) are shown as black arrows.
