Notes. The positions are measured relative to the lensing galaxy (at 0, 0). Given is the source component (Col. 1), the right ascension and declination at Epoch 1 (Cols. 2 and 3), the right ascension and declination at Epoch 2 (Cols. 4 and 5), the offset in right ascension and declination between Epoch 1 and Epoch 2 (Cols. 6 and 7), and the proper motion in right ascension and declination between Epoch 1 and Epoch 2 (Cols. 8 and 9).
