The Faint Sky Variability Survey II: Initial Results
نویسندگان
چکیده
We discuss the first results from the Faint Sky Variability Survey (Groot et al. 2000). The data consist of V -band light curves, BV I colours, astrometry, and morphology information on several hundred thousand point and extended sources in the magnitude range V = 17− 25. We discuss the first 30 survey fields covering an area of 8.4 square degrees towards moderate and high galactic latitudes. We analyse the quality of and discuss our differential photometry light curves. We employ statistical methods to select variable objects and present example variable light curves. The distribution of the colours and magnitudes of point sources in the survey is discussed and compared to galactic star count models. Finally, we discuss our search for trans-Neptunian objects in the FSVS fields observed towards ecliptic opposition.

The Faint Sky Variability Survey I: Goals and Data reduction process
The Faint Sky Variability Survey is aimed at finding photometric and/or astrometric variable objects in the brightness range between ∼16th and ∼24th magnitude on timescales between tens of minutes and years with photometric precisions ranging from 3 millimagnitudes for the brightest to 0.2 magnitudes for the faintest objects. An area of ∼23 square degrees, located at mid and high Galactic latit...
متن کاملThe Wisconsin H-Alpha Mapper Northern Sky Survey
The Wisconsin H-Alpha Mapper (WHAM) has completed a survey in Balmer α of the entire Northern sky above declination −30. This survey provides the first calibrated, velocity-resolved map of the Hα emission from the Galaxy. With one-degree spatial resolution, 12 km s−1 velocity resolution, and sensitivity to features as faint as 0.1 R (EM ∼ 0.2 cm−6 pc), this survey provides the deepest maps of t...
متن کاملThe Faint Sky Variability Survey I : An Overview
The Faint Sky Variability Survey is aimed at finding variable objects in the brightness range between 17th and 25th magnitude on timescales between tens of minutes and years with photometric precisions ranging from 3 millimagnitudes for the brightest to 0.2 magnitudes for the faintest objects. An area of at least 50 square degrees, located at mid-galactic latitudes, will be covered using the Wi...
متن کاملColor and Variability Characteristics of Point Sources in the Faint Sky Variability Survey
We present an analysis of the color and variability characteristics for point sources in the Faint Sky Variability Survey (FSVS). The FSVS cataloged ∼23 square degrees in BV I filters from ∼16–24 mag to investigate variability in faint sources at moderate to high Galactic latitudes. Point source completeness is found to be >83% for a selected representative sample (V=17.5– 22.0 mag, B − V=0.0–1...
متن کاملFirst Results from the Catalina Real-time Transient Survey
We report on the results from the first six months of the Catalina Real-time Transient Survey (CRTS). In order to search for optical transients with timescales of minutes to years, the CRTS analyses data from the Catalina Sky Survey which repeatedly covers twenty six thousand of square degrees on the sky. The CRTS provides a public stream of transients that are bright enough to be followed up u...
