Revised Flat Galaxy Catalogue (RFGC)
The Flat Galaxy Catalog (FGC) is the result of a systematic search for disk-like edge-on galaxies with a diameter larger than a=40arcsec and major-to-minor axis ratio a/b>7... -
Galaxy properties at NGP
A two-color study of the galaxies detected on POSS-I in a 289deg^2^ region centered on the North Galactic Pole is presented. We use a variety of mapping techniques to... -

This is an all-sky catalog of 4073 rich clusters of galaxies, each having at least 30 members within the magnitude range m_3_ to m_3_ + 2 (m_3_ is the magnitude of the third... -
Photometric rotation periods of stars in {alpha} Per
We present the results from a photometric monitoring program of primarily solar-type open cluster stars obtained during 1994 and 1995. Several members of the {alpha} Persei... -
FUSE observations in Magellanic Clouds
We present an atlas of stellar sight line data from the Far Ultraviolet Spectroscopic Explorer (FUSE) satellite for 287 stars in the Magellanic Clouds, obtained from eight years... -
NGC 129 positions and proper motions
Positions and magnitudes were derived for 537 stars in the area of the open cluster NGC 129. Combining these positions with data from the three other sources, proper motions... -
