The Automated Plate Scanner (APS) at the University of Minnesota is a unique high speed ‘flying spot’ laser scanner. It uses a rotating prism to scan the laser spot and a beam splitter to produce a pair of spots which scan across a pair of plates

Many of today’s most relevant astrophysical problems concerning galactic structure and dynamics, environmental effects on galaxy formation and maintenance, and the large-scale distribution of matter in the Universe are approached in a statistical f

We have identified several faint, red objects in the Hyades region which we believe are very low mass M dwarf and substellar mass brown dwarf members of the Hyades cluster. Proper motions for these stars, measured from Palomar Schmidt plates obtained

BVR photoelectric photometry and positions are reported for 437 stars in 49 Palomar Sky Survey fields. A relation is derived between the Johnson BVR photometry and the E and O photographic magnitudes on the Palomar plates. The BVR photometry, the E a
