Table 1: Initial radius, R, expansion speed, $v_{\rm exp}$ , and age, t, of the SNR for models with E = 10⁵¹ erg and $M = 10~M_{\odot}$ , as a function of the ambient density, n.
Table 2: Time evolution of the mass ( $M_{\odot }$ ) of cool clouds in remnants expanding into a surrounding medium with various density, flow speed, and ionization parameter. Columns 2-5 show results for an ambient density $n = 10^{5} ~{\rm cm}^{-3}$ . Columns 6-11 are for an ambient density $n = 10^{6}~{\rm cm}^{-3}$ . In Cols. 10 and 11 we give results for stationary surroundings but with either an enhanced AGN flux (causing a 10 $\times$ increase in the ionization parameter of the ambient medium to $\Xi \approx 1500$ ), or remnant parameters suitable for a type Ia SN explosion (see Sects. 3.5 and 3.6 respectively). Dashes indicate that no cool gas exists. The bottom row contains values for the integrated area under the mass vs. time curve, in units of $M_{\odot}~{\rm yr}$ .
Table 3: Statistics for the time-averaged line profiles shown in Fig. 11 ( $n = 10^{6}~{\rm cm}^{-3}$ ). Detailed are the profile centroid measures at different levels of the line peak, the full-width at half maximum ( FWHM), and the asymmetry index, ${A.I.} = ({C}({3\over 4})-{C}({1\over 4}))/{FWHM}$ . The columns labelled v₃₀₀₀, v₅₀₀₀, and v₇₀₀₀ refer to the models where the AGN wind speed is 3000, 5000 and $7000~{\rm km}~{\rm s}^{-1}$ respectively.
