... We publish 16 Doppler imaging temperature maps for the years 1994-2002 of the active RS CVn star II Peg. ... Through Doppler imaging we want to study the spot evolution of the star and in particular compare this with previous results showing a cyclic spot behaviour and persistent active longitudes. ... The derived temperature maps are quite similar to the ones obtained earlier with a different methods, the main differences occurring in the spot latitudes and relative strength of the spot structures....
... Only the lowest and highest bounds of the sequence of ranges are permitted to be of type UNDEFINED. For each range for which neither the lower or upper bound is of type UNDEFINED (ie, for each internal range in the sequence), the upper bound value must exceed the lower bound value unless both both bound types are INCLUSIVE, in which case the upper bound value may equal the lower bound value. In other words, each range must encompass some non-empty set of real numbers. ...
