Comparison of the absolute positions measured for TXS.E01 (contour plot of the peak channel) and for TXS.V01–TXS.V06 (crosses). Contours are 2, 3, 4, 5, 6 × 21.75 mJy beam⁻¹ and on the bottom left corner the EVN beam size is shown (see Table 1). Red crosses indicate the red-shifted H₂O maser features with respect to the systemic velocity of the galaxy ( km s⁻¹), and the blue cross the blue-shifted one. The size of the crosses correspond to the errors of the absolute positions.
