[C ii] spectra towards the H ii region, averaged over 156 (left) and 187 (right) pixels. The left panel represents the H ii region north of the Horsehead Nebula, the right panel represents the part south of the Horsehead Nebula. For the northern part, we obtain T_P = 1.0 K, FWHM = 8.7 km s^-1, and v_P = 14.1 km s^-1; for the southern part, a Gaussian fit yields T_P = 0.7 K, FWHM = 5.2 km s^-1, and v_P = 11.2 km s^-1.
