Notes. The columns give: name; spectral type; derived UV mass loss rate; mass loss rate expected for driving by a single line located at the SED emission peak in the single scattering condition; Hα mass loss rate; theoretical mass loss rates of Vink et al. (2001). The filling factor f∞ (see Sect. 3) is 0.1 for HD 46223 and HD 46150, 0.01 for HD 48099–1, and 1.0 (i.e. no clumping included) for all other stars.
