Notes. (1) Internal extinction, from Balmer decrement; (2) electron density, from [S II] line ratio; (3) wind half-light radius; (4) wind speed, assumed to be equal to the escape speed at r = rwind; (5) wind outflow rate, computed via Eq. (3); (6) mass-loading factor; (7)–(12) as in Cols. 1–6, but for the TES feedback scenario.
