Intensity maps centered on HOPS 372, HOPS 373, HOPS 394, and HOPS 397 integrated over the velocity ranges shown in the upper-left corner of each subfigure. Contour levels: between 5 and 75 K km s⁻¹ at intervals of 10 K km s⁻¹ for both CO J = 3–2 and J = 4-3 for HOPS 372 and HOPS 373, between 10 and 130 K km s⁻¹ at intervals of 15 K km s⁻¹ for HOPS 394 CO J = 3–2 and J = 4–3, between 5 and 60 K km s⁻¹ at intervals of 10 K km s⁻¹ for HOPS 397 CO J = 3–2, between 3 and 60 K km s⁻¹ at intervals of 10 K km s⁻¹ for HOPS 397 CO J = 4–3.
