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 #18,
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 #18 at the BeSSeL epoch on April 24, 2010, is: RA
(J2000) = 20h25m7
1051, Dec (J2000) = 34°49′57
589,
with an accuracy of ±1
mas.
