TASS Mark III Photometric Survey of the Celestial Equator
The Amateur Sky Survey (TASS) is a loose confederation of amateur andprofessional astronomers. We describe the design and construction of ourMark III system, a set of wide-field drift-scan CCD cameras whichmonitor the celestial equator down to 13th magnitude in severalpassbands. We explain the methods by which images are gathered,processed, and reduced into lists of stellar positions and magnitudes.Over the period 1996 October to 1998 November, we compiled a largedatabase of photometric measurements. One of our results is the tenxcatcatalog, which contains measurements on the standard Johnson-Cousinssystem for 367,241 stars; it contains links to the light curves of thesestars as well.
