Doppler images of II Peg. Panel a: temperature image. Panel b: magnetic-field image. ϕ is the rotational phase. Spot denominations in the top panel are: at phase ϕ = 0.25 the large cool feature is called spot A; at phase ϕ = 0.5 the equatorial cool feature is called spot B and the high-latitude warm feature spot C; at phase ϕ = 0.75 the cool feature is called spot D; and at phase ϕ = 0.00 the high-latitude warm feature is called spot E and the equatorial cool feature called spot F.
