Appendix A: Tables with multi-epoch line EWs and fluxes

Table A.1

Equivalent widths, Hα widths at 10% of peak intensity and Hα profile types on different observing Julian Dates.

Table A.2

Line fluxes on several observing Julian Dates for a subsample of the stars.

Appendix B: Mean spectra and relative variability distributions

thumbnail Fig. B.1

For each star and observing campaign, the mean spectra and relative variability distributions are plotted on the left side. The HeI5876, NaID, [OI]6300 and Hα regions are enlarged on the right side, for a better visualization. The mean spectrum is given by Ii,k, and the relative variability by σk/Irel,k, being σk = [(Ii,k − Irel,k)2]1/2. The subindex k refers to each spectral bin and the subindex i to each one of the N spectra per observing campaign. The relative variability plots provide information on the strength and wavelength position of the changes in the line intensity (Johns & Basri 1995).
