Top row: ALMA CO velocity channel maps toward RXJ1713NW-East. Each panel shows CO intensity distribution integrated every 2.0 km s−1 in the velocity range from −16.0 to −10.0 km s−1. Superposed contours indicate the same X-ray intensity as shown in Figure 1(b). Yellow crosses indicate positions of X-ray hotspots identified by Higurashi et al. (2020). The typical CO cloudlets, CL1–6, and a CO filament are also indicated. Bottom row: ALMA CO profiles of CL1–6 (black solid lines). Each spectrum is fitted by a single Gaussian kernel using the least-squares method.
