Column density a) and dust temperature b) profiles of B68 obtained at 500 μm resolution by applying the Abel inversion method to the circularly averaged intensity profiles observed with Herschel between 160 μm and 500 μm. a) Comparison between the column density profiles derived from the Abel reconstruction (solid black line) and LOS-averaged SED fitting (thick dashed line). The red curve shows the best-fit Bonnor-Ebert model to the Abel-inverted profile (see Table 2 for parameters). The vertical dotted line represents the half power beam radius of 363/2 (effective 500 μm resolution). b) Comparison of the Abel-inverted (solid line) and LOS-averaged SED (dashed curve) temperature profiles. The error bars represent the standard deviation of N_H2(r) and T_d(r) values obtained from independent profile reconstructions along sixteen angular directions.
