Abstract:
    Tables modified for testing. Added order specifiers "+=", "-=" and "+"
    to cols 5, 8 and 9 respectively and removed whitespace after "?" in 
    col 6.
    Beginning of original abstract follows:
    The present number of Galactic open clusters that have high resolution
    abundance determinations, not only of [Fe/H], but also of other key
    elements, is largely insufficient to enable a clear modeling of the
    Galactic disk chemical evolution. To increase the number of Galactic
    open clusters with high quality measurements, we obtained high
    resolution (R~30000), high quality (S/N~50-100 per pixel), echelle
    spectra with the fiber spectrograph FOCES, at Calar Alto, Spain, for
    three red clump stars in each of five Open Clusters. We used the
    classical equivalent width analysis method to obtain accurate
    abundances of sixteen elements: Al, Ba, Ca, Co, Cr, Fe, La, Mg, Na,
    Nd, Ni, Sc, Si, Ti, V, and Y. We also derived the oxygen abundance
    using spectral synthesis of the 6300{AA} forbidden line.

Description:
    Atomic data and equivalent widths for 15 red clump giants in 5 open
    clusters: Cr 110, NGC 2099, NGC 2420, M 67, NGC 7789.
