Tucker, K.D., R.L. Dickman, P.J. Encrenaz, and M.L. Kutner, 1976: The relation between carbon monoxide emission and visual extinction in cloud L134. Astrophys. J., 210, 679-683, doi:10.1086/154874.

Emission from the J = 1→0 transition of carbon monoxide has been mapped over an area of 40'×55' in cloud L134, and visual extinctions over the entire cloud have been obtained by means of star counts. Line intensities of ≥ 2 K are observable down to an extinction level of about one magnitude. From observations of the J = 1→0 transition of the ¹³CO isotopic species at 18 locations in the cloud, we have found a linear correlation between the local thermodynamic equilibrium (LTE) column densities of ¹³CO and magnitudes of visual extinction.
