Sgr A +50 km s^-1 Cloud, delineated by the integrated emission (+20 to +80 km s^-1) in the CS(5−4) line (contours), superimposed upon a 6 cm continuum map of the Sgr A Complex (colour image – red: nonthermal Sgr A East, yellow: thermal Sgr A West and the four compact H ii regions of which A is the northernmost, close to our observational position) (Serabyn et al. 1992). The FWHM Herschel 487 and 774 GHz beams, H (northernmost) and V polarizations, for the HOP observations we have carried out are indicated by red and yellow circles, respectively.
