Temperature and column density maps of G319.88+00.79. The left side of the figure concerns the dust temperature. a) The underlying grey image is the temperature map; the red contours correspond to temperatures of 19, 20, 21, and 22 K; the blue ones to temperatures of 14, 15, 16, 17, and 18 K. The 36″ beam of the temperature map (also that of the 500 μm map) is at the lower left. b) The underlying image is the column density map in false colours, showing the cold parental filament. c) The underlying image is the 8.0 μm emission map in false colours, showing the bipolar lobes. The right side of the figure shows the column density. d) The underlying grey image is the column density map; the red contours correspond to column densities of 1, 2, 4, and 6 times 10²² cm^-2. The 18″ beam of the column density map (also that of the 250 μm map) is at the lower left. The three clumps discussed in the text are identified. e) The underlying image is the 250 μm emission map in false colours. f) The underlying image is the temperature map in false colours.
