Beginning of ReadMe : II/271A TASS Mark IV patches photometric catalog, version 2 (Droege+, 2007) ================================================================================ TASS Mark IV Photometric Survey of the Northern Sky Droege, T. F., Richmond, M. W., Sallman, M. <Publ. Astron. Soc. Pac. 118, 1666 (2006)> =2006PASP..118.1666D =2007PASP..119.1083R (Addendum) ================================================================================ ADC_Keywords: Surveys ; Photometry ; Stars, variable Keywords: stars: general -- surveys Abstract: The Amateur Sky Survey (TASS) is a loose confederation of amateur and professional astronomers. We describe the design and construction of our Mark IV systems, a set of wide-field telescopes with CCD cameras which take simultaneous images in the V and I passbands. We explain our observational procedures and the pipeline which processes and reduces the images into lists of stellar positions and magnitudes. We have compiled a large database of measurements for stars in the northern celestial hemisphere with V-band magnitudes in the range 7<V<13. This paper describes data taken over the four-year period starting November, 2001. One of our results is a catalog of repeated measurements on the Johnson-Cousins system for over 4.3 million stars. This Version 2 of the catalog corrects a systematic error in photometry as function of Declination. Description: The Mark IV patches catalog contains summary information for sources detected simultaneously in V and I passbands on at least 5 occasions. The magnitudes in the table are the interquartile mean of all measurements, some of which may have been taken under poor conditions. In addition to the ordinary standard deviation from this mean, the table includes statistics based on ensemble analysis of stars within small patches one degree on a side; this removes some of the systematic errors in photometry and provides a more accurate estimate of intrinsic stellar variability.
