The column density profiles for the region marked with a dashed rectangle in Fig. 1d. The left hand frame shows the (thick black line), (thin blue line), and (dashed red line, excluding the central filament where the NIR emission becomes partly saturated) at the original resolution (40″, 30″, and 10″, respectively) without scaling. The x-axis is the offset along the stripe, from south to north. The dotted lines are the profiles of the maximum and minimum along the stripe. The right hand frame shows the same data at a common 40″ resolution, with values set to zero at offset 10′ (additive correction). The values have been scaled by a factor 1.3 to match the other curves on the northern side of the filament.
