Left: H2 column density map of Orion B at 18.2′′ angular resolution, derived from HGBS data. The contours correspond to AV ~ 3 (cyan) and 7 mag (black) in a column density map smoothed to a resolution of 2′. Right: dust temperature map of the Orion B region at 36.3′′ resolution, as derived from the same data set. Blue stars mark the NGC 2023 and 2024, NGC 2068 and 2071 HII regions and reflection nebulae, and the L1622 cometary cloud. The position of the Horsehead Nebula is also shown.
