$^{a}$  The number of CO lines measured in the $H$ band 
region, of which the number of weak lines (log~$W/\nu \la -4.75$) is 
given in the next column; 
$^{{b}}$ the same as $^a$ but in the $K$ band region;
$^{{c}}$ the same as $^a$ but for OH lines in the $H$ band
                        region;
$^{{d}}$ the same as $^a$ but for OH lines in the $L$ band
             		              region;
$^{{e}}$ with only 3 weak lines of similar intensities, the
		micro-turbulent velocity cannot be fixed by our
			 line-by-line analysis;
$^{{f}}$  N abundances based on CN 
(Aoki \& Tsuji \cite{Aoki97}) corrected for the effect of the revised C~abundances.
