Integrated intensity maps of the line emission for C₃H₆ and C₂ H₃CHO, summed over ± 0.5 MHz. The locations of IRAS 16293B continuum peak and the offset position are marked by the black star and plus sign, respectively. The blue contours start at 4σ and increase by steps of 4σ, where σ is 5 mJy beam⁻¹ km s⁻¹ for the integrated intensity. A representative beam of 0′′.5 is shown in the lower right corner of each panel.
