... Previous: Why Indexing the Sky is Desirable . ... An alternative algorithm, proposed here, is based on covering the sky with pixels of approximately equal area, and assigning a unique integer to each pixel. ... For each table, the pixel code value corresponding to the central position (RA, Dec) of each source is computed and inserted into a new column called PCODE. ... This cannot be the primary index of a table since PCODE values are not necessarily unique: one pixel may contain more than one...

Meta Index / Home Page / General source table layout There are columns for the Right Ascension and declination, position error, corrected Right Ascension and Declination, galactic longitude and galactic latitude. The corrected (RA_CORR and DEC_CORR) columns refer to the Right Ascensions and declinations with the astrometric correction applied (if correction successful). XMM-Newton SOC/SSC -- 2007-07-09

... The ChaMPlane survey is being conducted at the Harvard-Smithsonian Center for Astrophysics. The ChaMPlane team is conducting a "Bulge Latitude Survey" (BLS) to measure the latitude distribution of faint X-ray point sources in the region b = +/- 1.5њ, l = +/- 0.35њ centered at l = 0њ. ... In Chandra cycle 7, two-thirds of the region below the galactic plane were observed (BLS-Sa); observations of a similar-sized region above the plane (BLS-Na) are planned for cycle 8 (summer 2007). ...

ТљIn written science fiction, one often encounters another navigational convention, where towards the Galactic Centre is described as т??Corewardт??, away from the Centre towards the rim of the Milky Way is т??Rimwardт??, objects in the direction of the Galaxyт??s rotation are т??Spinwardт??, while objects in the opposite direction are т??antispinwardт?? ...

This form calculates which transits of the 1039 known transiting exoplanets are observable from a given location at a given time. Specify a time window, an observing location (either an observatory from the list or choose "Enter latitude/longitude" at the end of the list), and optionally any filters (e.g. minimum transit depth or elevation). The output includes transit time and elevation, and links to further information about each object, including finding charts and airmass plots. ...
