Fig. A.2.
Multi-epoch Hα spectra of LkCa 15 taken with the telescopes indicated. The red dotted lines are the individual spectra and the black solid lines the corresponding averages. The vertical dashed and dotted lines indicate the position of the central dip in the middle (~−50 km s−1) and upper (~ + 15 km s−1) panels, respectively. The spectro-astrometric analysis in this work corresponds to the data in the middle panel.
