Table 1: HCN(1-0) line parameters, obtained at the various peak (i.e., not spatially integrated) by fitting a Gaussian profile to the (naturally weighted) data. Errors include uncertainties of the fit and calibration. a From Schinnerer et al., in prep. b From uniformly weighted maps to avoid contamination by the ring emission. cSpatially integrated over the entire area of $\pm $9''; d In mJy; e in Jy km s-1.
