Profiles obtained from the Planck maps of the Helix at 217 (dash dot line), 353 (dashed line), 545 (dotted line), and 857 GHz (continuous line), with cuts at the same PA as in Speck et al. (2002). The direction along which the cuts were performed is indicated in the small inset on the top left (superimposed on the 857 GHz Planck map, in equatorial coordinates). The Planck profiles are compared to the 160 m profile reported in Speck et al. (2002) (triple dot dashed line).
