Description:
We present Stroemgren uvby and H_{beta}_ photometry for a set of 575
northern main sequence A type stars, most of them belonging to the
Hipparcos Input Catalogue, with V from 5mag to 10mag and with known
radial velocities. These observations enlarge the catalogue we began
to compile some years ago to more than 1500 stars. Our catalogue
includes kinematic and astrophysical data for each star. Our future
goal is to perform an accurate analysis of the kinematical behaviour
of these stars in the solar neighbourhood.

Note (1): see individual notes below
Note (2): '*' means that we performed only Hbeta for this particular star.
uvby were taken from Hauck&Mermilliod catalogue
Note (3): the following symbols are used:
D: information about duplicity for optical pairs with separation
less than 20 arcsec.
V: information about variability.
B: spectroscopic binary or variable radial velocity in Renson 1991
(Catalogue general des etoiles Ap et Am, Univ de Liege,
CDS Catalogue <III/162>).
C: the star is member of a cluster. Identification is given in
the notes.
O: other remarks (see below).
