Integrated intensity maps toward Sgr B2(N2) of a) CH₃NHCHO 9_2,8–8_2,7, b) CH₃NCO 10_1,10–9_1,9, c) NH₂CHO ν₁₂ = 14_0,4–3_0,3, d) NH₂¹³CHO 4_0,4–3_0,3, e) HNCO 4_3,1–3_3,0 and 4_3,2–3_3,1, and f) CH₃CONH₂9_0,9–8_1,8, 9_1,9–8_1,8, 9_0,9–8_0,8, and 9_1,9–8_0,8. The position of Sgr B2(N2) is marked with a large cross. The smaller cross indicates the position of Sgr B2(N1). Because of the different systemic velocities of the two sources, the line assignment is only valid for Sgr B2(N2), inside the dashed box. The contours start at 4σ and increase by a factor of 2 at each step. The dashed (blue) contour is at −4σ. The value of the rms noise level, σ, is given in mJy beam^-1 km s^-1 in the top right corner of each panel. The mean frequency of the integration range in MHz and the synthesized beam are shown in the bottom right and left corners of each panel, respectively.
