Bottom panel: G097.53+3.18-Hii. The gray-scale image shows the JVLA A-Array (Gaussian-tapered) C-band continuum, using gray-tone steps that increase linearly with the map intensity from 0.46 to 4.6 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 0.54 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 0.25 mJy beam^-1. Top panel: G097.53+3.18-M. The gray-scale image shows the JVLA A-Array C-band continuum (produced selecting uv-projected lengths ≥100 kλ), using gray-tone steps that increase linearly with the map intensity from 0.014 to 0.14 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 0.16 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.
