We use the recently published \\ha data of both the northern and southern skies as the basis for such a template.\n  The first step is to correct the \\ha maps for dust absorption using the 100 $\\mu$m dust maps of Schlegel, Finkbeiner & Davis (1998). We show that for a range of longitudes, the Galactic latitude distribution of absorption suggests that it is 33 per cent of the full extragalactic absorption.
