Notes. Adopted absolute (A(X)) solar values are also reported. Numbers in parenthesis indicate the number of lines from which the abundance is derived and the abundance Gaussian σ value, when the abundance is derived from more than one line. The two values for the carbon and nitrogen abundances for Star #3416 are derived from the G-band and C2 band at 563.5 nm and from the CN lines at 634 nm and 800 nm. 12C/13C isotopic ratio was measured from CN lines at 800 nm.
