Channel map of the CH₃OH maser emission toward S255IR-SMA1. The CH₃OH emission is shown in contours, with levels at 0.6, 1.2, 1.8, 2.4, 3.0, 3.6, 4.2, 4.8, and 5.4 Jy/beam. The continuum emission at 335 GHz is displayed in grayscale. The datacube has a channel width of 0.42 km s^-1, and maps of only every other channel starting from that at –1.02 km s^-1 are shown. Positions of the 5 GHz radio continuum and those of the pre-burst and after-burst CH₃OH maser clusters reported by Moscadelli et al. (2017) are labeled for reference by the cross, P, and A, respectively, in the first and last channel. The synthesized ALMA beam is shown in the lower left corner.
