Maps of 6.7 GHz methanol maser in G22.357+0.066 obtained with the EVN at two epochs; MJD 4981 a) and MJD 4264 (b), adapted from Bartkiewicz et al. 2009). The coordinates are relative to the brightest spot. The sizes of symbols are proportional to the logarithm of the brightness of maser spots. The colors of circles relate to the LSR velocity scale presented in the wedge. The groups of spots are also labeled by their central velocities or the velocity ranges. The linear scale, derived for the distance of 4.86 kpc, is shown by the horizontal bar.
