M31STARS - M31 Field Brightest Stars Catalog
Thie database table is a catalog of 11438 stars in the field of M31 and
8778 stars in 2 nearby "foreground" fields. It is based on a set of
Tautenburg Schmidt plates in U, B, V, and R taken by van den Bergh.
The range of visual magnitudes of stars is 11.5 < V < 20.

There are 2 values for this parameter: M31 FIELD means that the star
lies within an irregularly shaped field centered on M31, while FOREGROUND
FIELD means that this stars lies within 1 of 2 nearby foreground fields on
either side of the M31 field. (See Fig. 1 of Berkhuijsen and Humphreys 1989,
Astronomy and Astrophysics, Vol. 214, page 68 for an illustration of these
fields). A star which is in the M31 field may still be a foreground object,
notice. Indeed, Berkhuijsen and Humphreys estimate that only about 2660 of
the 11438 stars in the M31 field are actually members of M31.
BROWSE classification type. The classification is based on the `Type`
parameter, if one is available.
