Table A.1.

Journal of the spectroscopic observations of the LBV-like stars in our sample. The first column gives the heliocentric Julian date. The following columns provide for each spectral line or region the measured RVs (in km s −1) and the average values are given in the last column. The asterisk marks the epoch used as template for the cross-correlation. The full table is available electronically at the CDS.
