Notes. The first and the second column give the targets and the observation dates, respectively. The third, fourth and fifth column give the LSD parameters introduced in Sect. 3.1 The last columns give the values of the longitudinal magnetic field and the 1σ level for each LSD profile, and the associated statistical threshold flag (as described in Sect. 3.1). The * for μ Cep observations indicates that they are plagued by spurious polarisation (see Sect. 3.4.2) and therefore we did not compute the longitudinal magnetic field. The † indicates that the LSD statistics and the estimation of Bℓ were performed on the cleaned profiles of μ Cep (see Sects. 3.4.2 and 4.1).
