Notes. Columns 1 and 2 give the date, Universal Time (UT) and Heliocentric Julian Date of the observations. Columns 3 and 4 give the total exposure time and the number of polarimetric sequences. Columns 5 and 6 give the peak S/N per CCD pixel (at ~501 nm for HD 130807 and at ~518 nm for HD 122451 and HD 105382) in the spectra, and the S/N per 1.4 km s-1(for HD 130807 and HD 105382) and 4.2 km s-1(for HD 122451) pixels in the LSD Stokes V profiles. Columns 7–9 give the longitudinal magnetic field, the magnetic detection probability, and the detection type (see text).
