Parameters of characteristic spot solutions discussed in the text; longitudes and colatitudes are given for the spot center.

^a BC, BN and BS stand for ``bright central'', ``bright north'' and ``bright south'', respectively. They describe spots with colatitudes close to the center of the planetary disk. DN and DS stand for ``north'' and ``south'' dark spot solutions, respectively; DEQ represents a ``dark'' spot centered below the equator. ^b Relative to the photosphere. ^c Fraction of total stellar surface.
