Integrated emission maps in ranges of 1 km s⁻¹ for the C¹⁸O 2 →1 line (top panels) and ¹³CO 2 →1 line (bottom panels). The red lines in the top panels depict the brightest features of the C¹⁸O emission, and mark the possible path that the gas follows to reach the stellar cluster, indicated with a white star. The white lines in the bottom panels mark the “skeletons” of the filaments identified by DisPerSE in the ¹³CO and C¹⁸O 1 →0 maps.
