Discussion
==========

When employing UV wind lines as mass loss diagnostics, only unsaturated wind lines are useful. However, Prinja & Massa (2010) have shown that the optical depths of apparently unsaturated wind lines may be strongly affected by porosity, causing mass loss rates derived from UV wind lines to under estimate the actual mass loss.
