Comparison between the total intensity spectra (I) of the H₂O gigamaser detected toward TXS 2226-184 with the GBT in epoch 2010.94 (black histogram) and the combination (red dot-dashed line) of the 11 Gaussian components determined for the six H₂O maser features (TXS.V01–TXS.V06) detected with the VLBA in epoch 2017.45. The red arrows indicate the velocities of the total intensity peak of the different maser features (see Table 3). The dashed black line indicates the systemic velocity of the galaxy in the radio convention (7270 km s⁻¹).
