The velocity field of the 6.7 GHz methanol masers as obtained from a first moment map of the bright methanol emission (colour) with labels a–i overlaid on K band continuum (contours) (Torrelles et al. 1998). The filled circle indicating the weak feature i has been added to the moment map manually based on the results of detailed fitting of each channel. Also shown are the 12.2 GHz methanol masers (circles) in this paper and (boxes) Min01, and 22 GHz water masers (small pluses) (Vlemmings et al. 2006). The position of the protostar is indicated by the large plus sign (Curiel et al. 2006).
