Notes. The columns indicate the maser feature name, right ascension offset, declination offset, identified component from the Gaussian fit, peak flux density, peak velocity (radio convention), linewidth of the maser feature, spectral noise per channel, signal-to-noise ratio, spectral noise per km s−1, integrated flux, isotropic luminosity.
Isotropic luminosities are derived from LH2O/[L⊙] = 0.023 × ∫S dV/[Jy km s−1] × D2/[Mpc2], where D = 107.1 Mpc (derived assuming H0 = 70 km s−1 Mpc−1, Kuo et al. 2018).
