Integrated intensity maps (contours) on top of the continuum at 330 GHz (color; rotated clockwise by PA = 21°, top) and integrated 1d-spectra (bottom) of the three molecular transitions with compact emission from the close surroundings of QX Pup (clump S). The coordinates of clump S are RA = 07^h42^m16. s915 and Dec = −14°42′50.′′06 (J2000). The position of clump S has been adopted as the origin of positional offsets in these and all subsequent figures illustrating image data. Gaussian fits to the line profiles (dashed lines) are shown together with the line centroids and full width at half maximum (bottom).
