AMBER (LR-HK) squared visibilities as a function of the spatial frequency. The legend denotes the epoch and the position angle (PA) of the baseline of the observation. All 2007 and 2008 data have a similar PA because the same co-linear baseline configuration was used. Per baseline, the H and K band are separated by the HK-discontinuity, but still show a smooth transition between the two.
