Comparison between the multiple populations discovered in NGC 2547 and Gamma Vel B. The top panel shows the EW(Li) as a function of V − I, while the bottom panel shows a V vs. V − I CMD. Photometry has been corrected according to the extinction towards NGC 2547 (E(B − V) = 0.06) and Gamma Velorum (E(B − V) = 0.055). The x-axis on the top reports an effective temperature scale derived from V − I, using the colour-temperature transformations described in Pecaut & Mamajek (2013). In both panels empty squares, filled red circles, and blue circles indicate the stars of Gamma Vel B, NGC 2547 B, and NGC 2547 A respectively. EW(Li) upper limits in NGC 2547 A are reported with downward triangles. Only a subsample of stars of NGC 2547 is shown, since V band photometry is not available for all targets (see footnote on page 4).
