Table 1: Candidate members of NGC 2451 A (upper part) and B (lower part), of which high-resolution spectra were taken. Magnitudes, de-reddened colours, spectral types, and X-ray parameters are taken from HWS.
Table 2: Measured Fe I equivalent widths in mÅ.
Table 3: Derived iron abundances for selected stars of the NGC 2451 A and B clusters.
Table 4: Results of detailed spectral analysis: lithium equivalent widths and derived abundances, H $\alpha$ appearance and effective temperatures.
