From top to bottom, in the two-square-degree field of the GRS where CS is observed, integrated intensity maps of the total (noise+detection) CS emission, of the detected CS emission, of the noise in the CS cubes, of the diffuse (¹²CO-bright and ¹³CO-dark), dense (¹²CO-bright, ¹³CO-bright, and CS-dark), and very dense (¹²CO-bright, ¹³CO-bright, and CS-bright) ¹²CO components.
