Fig. 3

Three hundred cores in the California molecular cloud plotted in the H 2 column density map. This map is shown from 0 to 10% of the peak value (8.4 × 1022 cm−2). The cores are displayed with the measured dust temperature in units of K, coded as shown in the color bar on the top. The major and minor axes of the core ellipse shape in this map are 4 FWHMs of the equivalent Gaussian.
