Errors in parenthesis. ^a Total integration time (8 $\times$ individual integration time by waveplate position); ^b signal-to-noise ratio per pixel for the unbinned spectra; ^c mean values for the full spectrum (6300-6800 $\rm\AA$ ) binned with a polarization error (per bin) of 0.1%. The quoted polarization error is the average error per bin and the PA error is given by 28.65 $\times\sigma_{P}/P$ (Serkowski 1974).
