Gray-scale image: JVLA A-Array C-band continuum, using gray-tone steps that increase linearly with the map intensity from 0.023 to 0.23 mJy beam^-1. The JVLA A-Array Ku-band continuum is represented with cyan contours with plotted levels −10% and from 10% to 90%, in steps of 10%, of the peak value of 0.19 mJy beam^-1. The white contours reproduce the JVLA A-Array K-band continuum, plotting levels −20% and from 20% to 90%, in steps of 10%, of the peak value of 0.22 mJy beam^-1. Colored dots and arrows have the same meaning as in Fig. 1. The amplitude scale for the maser velocity is indicated by the black arrow in the bottom left of the panel. The white cross gives the (velocity-averaged) position of the 6.7 GHz methanol masers, detected at low velocity resolution in the C-band.
