We present H line profiles (
,
at
continuum level,
for some objects) for 58 stars in 8 northern open
clusters and associations, complemented with H
and H
profiles
for 36 of them as well as H
and H
for 16 programme stars.
Our
observations, though lower in resolution, yield results which are in good
agreement with those obtained
in earlier works based mainly on field Be stars. Our data suggest a similar
spectroscopic behavior for both field and cluster Be stars.
The line parameters (EW, FWHM, ) have been obtained for each
line. Nearly the whole set of stars have previously published
quasi-simultaneous
photometry,
so a study of reliable correlations between photometric
and spectroscopic data can be undertaken.
