- Abstract
The All Sky Automated Survey (ASAS) constantly monitored the entire southern sky and part of the northern sky to about δ<+28°. The third phase of the project, ASAS-3, lasted from 2000 until 2009 (Pojmanski 2002, Cat. II/264).
The employed instrumentation, which was situated at the 10inch astrograph dome of the Las Campanas Observatory in Chile, consisted of two wide-field telescopes equipped with f/2.8 200mm Minolta lenses and 2048*2048 AP 10 Apogee detectors that covered a field of sky of 8.8°*8.8°. About 107 sources brighter than V~14mag were monitored in Johnson V. The achieved CCD resolution was about 14.8''/pixel, which led to an astrometric accuracy of around 3''-5'' for bright stars and up to 15.5'' for fainter stars.
An initial list of target stars was created by selecting CP2 stars or CP2 star (the magnetic Bp/Ap stars) candidates and He-weak (CP4)/He-strong objects from the most recent version of the Catalog of Ap, HgMn, and Am stars (Renson & Manfroid 2009, Cat. III/260).
