Schematic drawing of the R CrA cloud and its surroundings. Protostars are shown in yellow. Red structures indicate extended H₂CO and CH₃OH emission, and blue striped structures show extended emission from hydrocarbon and nitrogen-bearing species (Miettinen et al., in prep.; Lindberg & Jørgensen 2012). The brown dashed contour shows extended high-J (J ~ 20) CO emission, and the black dotted contours show extended 110 μm dust continuum emission not associated with the point sources (from Herschel PACS observations; Lindberg et al. 2014b). The solid black circle shows the APEX beam at 218 GHz centred at IRS7B, and the dashed black circle shows the APEX beam at 363 GHz. Large parts of the region have not been covered by all observation modes, and thus the map is probably incomplete. This map covers only a small part of the sources in the CrA source survey (cf. Fig. 1). (A colour version of this plot is available in the online Journal.)
