Notes. Column 1 gives the feature label number; Col. 2 lists the observing epochs at which the feature was detected; Cols. 3 and 4 provide the intensity of the strongest spot and the intensity-weighted LSR velocity, respectively, averaged over the observing epochs; Cols. 5 and 6 give the position offsets (with the associated errors) along the RA and Dec axes, relative to the persistent feature #2, measured at the first epoch of detection; Cols. 7 and 8 give the components of the absolute proper motion (with the associated errors) along the RA and Dec axes. The absolute position of the feature #2 at the BeSSeL epoch on May 16, 2010, is: RA (J2000) = 22h16m103699, Dec (J2000) = 52°21′34229, with an accuracy of ±4 mas.
