T analysis: a) line-by-line analysis of CO lines in Star 4, i.e. logarithmic abundance corrections to the assumed carbon abundance derived from the observed log W/ν values are plotted against the log W/ν values for vmic = 3, 4, and 5 km s-1; b) confirmation of the null abundance corrections for log AC/AH = −3.56 and vmic = 3.93 km s-1.
