**Table 4:** Stellar parameters used as input for the GASTRoNOoM-code. The terminal velocity, $v_{\infty }$ , is derived from the CO lines; the stellar radius from the stellar luminosity and temperature. The envelope density decreases as $\sim$ r^-2. Literature references are given in the footnote.
