VizieR Online Data Catalog: HD50138 time-dependent spectral variations (Jerabkova+, 2016)

The catalogue presents spectra and measured quantities (Equivalent widths EW, Radial Velocities RV and Relative Fluxes F) of HD 50138 (V743 Mon) obtained within years 1993-2013. We obtained data from four different observatories - 1.06 m at Ritter Observatory (RO, echelle, R~26000, 32 spectra, 1994-2003), the Perek 2 m telescope at Ondrejov Observatory (OO, slit, R~12500, 56 spectra, 2004-2013), the 2.12m telescope at Observatorio Astronomico Nacional San Pedro Martir (SPM, echelle, R~18000, 16 spectra, 2005- 2013), and the 0.81m telescope at Three College Observatory (TCO, echelle, R~12000, 26 spectra, 2013-2014). We use IRAF procedures for spectral reduction and normalization (details in the A&A paper). The heliocentric correction is applied at all presented data.

Note: The oxygen line from Ritter observatory (date 2449399.685) is double peaked. For that reason its measurements are not used for further analysis in A&A paper.
