 Note: index $N$ indicates the north polar cap, $S$ the south
polar cap. Longitude, $\ell_{\rm N/S}$, is counted from 0 (a time of
maximum positive radial velocity of the primary according to
Table~\ref{tbl-spectro}) to 360$^\circ$ in the same direction as the
orbital motion. Latitude, $b_{\rm N/S}$, is counted from 0~=~equator
to $\pm$$90^\circ$~=~poles; radius, $r_{\rm N/S}$, in degrees (circular
spots); fractional area, $A_{\rm N/S}$, in per cent of the entire
stellar surface and the spot temperature ($T_{\rm spot}$) in Kelvin
(for light-curves with good $VI$ data; note that the photospheric
temperature is 4500~K). Individual spot temperatures are assumed to
be identical.
