Notes. The first column recaps the name of the observed targets and the second and the third columns give the dates of the observations (Heliocentric Julian date and Gregorian calendar, respectively). The fourth column displays the total exposure time for a single Stokes V sequence (combination of four sub-exposures). The fifth column gives the number of Stokes V sequences collected for each observational date. Finally the last column gives the mean maximum S/N reached in an individual Stokes V spectrum. The exponent a for the star μ Cep, indicates the technical observations presented in Sect. 3.4.2.
