Gray-scale image: JVLA A-Array C-band continuum, using gray-tone steps that increase linearly with the map intensity from 0.016 to 0.16 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 0.20 mJy beam^-1. This source was not observed in the K-band by the JVLA. 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.
