\caption{Physical and atmospheric parameters for the RGB stars in NGC~2808
used for the present study. The temperatures, luminosities, and gravities 
listed in Cols.~3--5 are derived from the ($V-K$) colours (see Sect.~2). 
The expansion velocities and mass loss rates in Cols.~11
and~12 are discussed in Sect.~4.1.
