Distribution of the 6.7 GHz CH₃OH masers toward NIRS 3. Circles and triangles represent maser spots before and after the outburst, respectively. Relative maser positions between the two epochs are accurate within a few mas. Note that the apparent motion of the 6.7 GHz CH₃OH masers in NIRS 3 between the two EVN epochs is negligible (Rygl et al. 2010). The symbol size varies logarithmically with the maser brightness, and colors indicate the maser V_LSR according to the right-hand scale. Letters “A” and “P” are used to label prominent maser clusters. The gray-scale image shows the velocity-integrated emission of the 6.7 GHz masers observed with the JVLA A-Array on 2016 October 15. The corresponding intensity scale is given at the top. The JVLA 5 GHz continuum emission is drawn with red contours. The rms noise of the image is 12 μJy beam^-1. Contour levels are 0.11, 0.15, and from 0.22 to 2 mJy beam^-1 in steps of 0.22 mJy beam^-1. The synthesized beam of the continuum map is 0.′′25 × 0.′′24 at PA = 51°.
