Open clusters in APOGEE and GALAH: Combining Gaia and ground-based
  spectroscopic surveys
  Context: Open clusters are ideal laboratories to investigate a variety of
astrophysical topics, from the properties of the Galactic disk to stellar
evolutionary models. Knowing their metallicity and possibly detailed chemical
abundances is therefore important. However, the number of systems with chemical
abundances determined from high resolution spectroscopy is still small.\\ Aims:
To increase the number of open clusters with radial velocities and chemical
abundances determined from high resolution spectroscopy we used publicly
available catalogues of surveys in combination with Gaia data.\\ Methods: Open
cluster stars have been identified in the APOGEE and GALAH spectroscopic
surveys by cross-matching their latest data releases with stars for which
high-probability astrometric membership has been derived in many clusters on
the basis of the Gaia second data release.\\ Results: Radial velocities have
been determined for 131 and 14 clusters from APOGEE and GALAH data,
respectively. This is the first radial velocity determination from high
resolution spectra for 16 systems. Iron abundances have been obtained for 90
and 14 systems from APOGEE and GALAH samples, respectively. To our knowledge 66
of these clusters (57 in APOGEE and 9 in GALAH) do not have previous
determinations in the literature. For 90 and 7 clusters in the APOGEE and GALAH
samples, respectively, we have also determined average abundances for Na, Mg,
Al, Si, Ca, Cr, Mn, and Ni.
