Scientific paper

We report spectroscopic and photometric observations of ten δ Scuti stars and one eclips- ing binary from the open cluster NGC 1817, and three δ Scuti stars from the open cluster NGC 7062. For each target, we measure the projected rotational velocity, v sin i, the radial velocity, RV , the effective temperature, Teff , and the surface gravity, log g. All stars are found to be moderate or fast rotators. We classify three targets as new single-lined spectroscopic binaries and one target as a double-lined spectroscopic binary.
