Taurus MC as seen in carbon monoxide, ¹²CO(J = 1 → 0) and ¹³CO(J = 1 → 0) emission from Goldsmith et al. (2008), neutral atomic hydrogen (H I) emission from GALFA-H I DR2 (Peek et al. 2018), volume density of hydrogen nuclei (n_H) across distances derived from the 3D dust reconstruction in Leike et al. (2020), and hydrogen nuclei column density (N_H) derived from the dust optical depth at 353 GHz (τ₃₅₃) obtained with the Planck observations (Planck Collaboration XI 2014). The contours correspond to N_H = 5 × 10²¹, 8 × 10²¹, and 1.25 × 10²² cm⁻². The labels in the bottom panel indicate the reference positions for the most prominent objects in Lynds’ catalog of dark nebulae (Lynds 1962) and Barnard’s catalog of dark objects in the sky (Barnard 1927).
