Notes. The table gives statistical errors. Additional systematic uncertainties are about 5%. Additional 1σ uncertainty on the positions can be derived from the Reid et al. (1988) relation, Δθ(″) = σbeam/ (2 × SNR). Parameters are derived from point or circular Gaussian function fit of the visibilities averaged in the corresponding velocity ranges.
