Bipolar nature of Sh 201. Red is for the column density map; the red contours are of column density; the peak column density is 6.2 × 10²² cm^-2 (east condensation) and the contours levels are 0.1, 0.25, 0.5, 1, 2.5, and 5 × 10²² cm^-2. Turquoise is for the Spitzer 8.0 μm image showing the PAH emission from the vicinity of the ionization front. The coordinates are J2000 in degrees.
