a) Integrated intensity map of the CH emission from 5.0 to 7.2 km s^-1. Contours show every 0.1 K km s^-1 from 0.1 K km s^-1. b) Integrated intensity map of the broad component of the CH emission (4.7−5.8 and 6.6−7.2 km s^-1). Contours show every 0.1 K km s^-1 from 0.2 K km s^-1. c) Integrated intensity map of the narrow component of the CH emission. Since the narrow component velocity slightly changes in a large scale, the 0.2 km s^-1 span centered at the peak velocity is integrated to extract the narrow component. Hence, it should be noted that a part of the broad component is contaminated. Contours show every 0.05 K km s^-1 from 0.1 K km s^-1. Filled circle, filled square, open square, star, cross mark, and x symbols correspond to the position of the CI peak, TMC-1(CP), TMC-1(NH₃), L1527, TMC-1C, and TMC-1A, respectively, as shown in c).
