The integrated intensity maps of CH₃OH, CH₃NH₂, and CH₂NH transitions in G10.41+0.03. The rms noise level, δ Jy beam⁻¹, is shown at the top right. The positions of continuum sources (Wood & Churchwell 1989; Cesaroni et al. 1998, 2010) are shown by circles. The triangles show the positions of hot cores, where the spectra were extracted. The velocity ranges are from 57.6 to 71.3, from 58.8 to 67.1, and from 62.9 to 76.6 km s⁻¹ for CH₃OH, CH₃NH₂, and CH₂NH, respectively. The upper energy level is shown at the bottom left of the figures.
