Three-color image (blue = radio continuum at 20 cm; green = 4.5 μm; red = 8 μm). The radio sources RS2, RS3, and RS4 are indicated, and between brackets the nomenclature of the associated infrared sources is indicated: WISE J182411.60-122726.0 (IR2), J182413.49-122730.0 (IR3), and J182412.89-122742.2 (IR4). The contours represent the ¹³CO J = 3–2 emission integrated between 10 and 30 km s^-1 with levels of 10, 15, and 30 K km s^-1.
