Young sources at the waist of Sh 201. Top: unsharp-mask 100 μm image of the eastern portion of the waist of Sh 201 showing the presence of two point sources. Middle: same but deeper image with the column density contours in green showing the dense condensation east of Sh 201. The column density contour levels are 10²², 3 × 10²², 4 × 10²², 5 × 10²², and 6 × 10²² cm^-2); the red contours are for the 100 μm emission (levels of 0.5, 1.0, 1.5, and 2.0 Jy/beam). Bottom: the 100 μm contours are superimposed on the Spitzer 4.5 μm image showing the stars discussed in the text. The coordinates are J2000.
