Notes.

^(a)

Based on Gaussian profiles fit to coadded lines;

^(b)

relative to velocity of ¹³CO and C¹⁸O absorption;

^(c)

from spectrum obtained in August 2008;

^(d)

forced value from same component in v = 2−1 or ¹³CO transition;

^(e)

fit only to red emission;

^(f)

fit is not good because line is not Gaussian;

^(g)

March 2010;

^(h)

tentative classification as narrow component.
