Notes.
Calculated from two-dimensional Gaussian fits to the integrated intensity emission using the AIPS task IMFIT which deconvolves the clean beam from the fitted component size. The accuracy and errors of this process are discussed in Condon (1997).
From Gaussian fits where the line is blended with HCO+. Limits to HCN-VIB brightness temperatures are TB (HCN-VIB) > 20 K for IC 860, >6 K for Zw049.057, >8 K for IRAS 17208-0014 and 68 K for Arp220W. For IC 860 and Zw049.057 1′′ = 286 pc, for Arp220W 1′′ = 388 pc and for IRAS 17208-0014 1′′ = 853 pc.
