Notes. For each identified feature, the label (given in Col. 1) increases with decreasing brightness. Columns 2, 3, and 4 report the LSR velocity and brightness of the brightest spot and its percent brightness variability. Columns 5 and 6 give the position offset relative to the feature # 2, in the east and north directions, respectively. Columns 7 and 8 report the projected components of the feature proper motion relative to the center of motion (as defined in Sect. 5.4, and identified with label # 0), along the east and north directions, respectively. Column 9 shows the relative error of the proper motion amplitude. The absolute position of the reference feature # 2 is reported at the bottom of the table.
(a) Variability (%) = ( $F_{\rm MAX} - F_{\rm MIN}$of the brightest spot) / (( $F_{\rm MAX} + F _{\rm MIN}$)/2.0).
