Left: single-dish IRAM 30 m images of the area around HBC 722 in different lines, and a Herschel/SPIRE 350μm continuum image of the same area. For the IRAM data, the colors show the integrated line intensity, and the scale extends from 0 to I_max, where I_max is 25.0, 2.9, 1.4, 3.1, 6.2, 1.4, and 0.25 K km s^-1 for the ¹³CO J = 1−0, C¹⁸O J = 1−0, C¹⁷O J = 1−0, CN N = 1−0, CS J = 2−1, HC₃N J=12–11, and HNCO J_{K-1K+ 1} = 5₀₅–4₀₄ lines, respectively. For the Herschel image, the scale extends from 0 to 1050 MJy sr^-1. The asterisk, plus, diamond, and triangle mark the positions of HBC 722, MMS1, MMS3, and MMS4, respectively. Circles in the bottom left corners of the top and bottom panels mark the beam sizes of the IRAM 30 m telescope and Herschel. Right: profiles of the lines averaged over the areas displayed in the left column (black histograms), with fitted Gaussian functions (red curves).
