Flux-calibrated images of 103P/Hartley 2 in a look-up table to display the isophote anisotropies. The images are acquired with clear continuum filters centred at 443 nm with cuts between 0 and 2 × 10-15 erg cm-2 s-1, and at 684 nm with cuts between 0 and 8 × 10-15 erg cm-2 s-1. The third column shows the quotient of the comet images obtained a few hours apart (i.e. 2nd column/1st column) with cuts between 1 and 1.6. The fourth column displays the radially renormalized images of the ones in the second column. The FOV is 62.5″ × 62.5″, meaning 5800 × 5800 km at the comet’s distance.
