Fig. 5


Resulting fits to the water maser spots detected toward I16293 (see Table 5). The black, red, and yellow lines show the best fits for spot 1, 2, and 3, respectively. The solid squares with the error bars indicate measured positions and their corresponding uncertainties. The solid circles mark the expected positions from the fits at the observing epochs. Top left: individual fits to each of the three maser spots. Top right: simultaneous fit assuming that the parallax is the same for the three spots. Bottom left: simultaneous fit to positions of Spot 1 and 2, by allowing them to have a positional offset and different proper motions. Bottom right: simultaneous fit to spots 1 and 2, assuming that they belong to the same cloudlet.
