Fig. 2

Detail of polarised spectrum with continuum normalisation of WD 0011-721, obtained with the FORS2 instrument with grism 1200R. Here we show I and V (normalised to 1.0 in the I continuum, with V shifted upwards by +0.65 for clarity) rather than I and V∕I, in order to make clear the relative amplitude of the Stokes components I and V. The null profile is also shown offset by + 0.55%.
