XMM-Newton Science Analysis System . ... Meta Index / Home Page The position of a source on the image ( XPOS and YPOS ) are referred to a coordinate origin in which the pixel at the far-left and bottom of the image has coordinates 1.0, 1.0. The coordinates are computed using the first-order moments of the intensity profile, and the algorithm is similar to that used in the sextractor program (please see the sextractor manual for a detailed discussion). XMM-Newton SOC/SSC -- 2008-10-22 ...

This diagram illustrating Bonne's projection with conformal latitude +35 was produced by WCSLIB , a C implementation of the coordinate transformations defined in the FITS WCS papers. ...

... Coordinate system . It is necessary to specify the coordinate system for the drilling of plug-plates so that the drilling file (currently named plPlugMap), plate drilling, cartridge, rotator wrap and the rotator itself are compatible. ... The TCC rotator angle (object system) is defined to be 0 degrees for this orientation. ... Thus, the rotator angle gives the conventional astronomical position angle on the sky of the y axis (although Russell won't acknowledge this necessarily). ...

The aim of this section of the course is to familiarise you with celestial Coordinates. ... I found some good notes explaining the celestial coordinate system on the web: . ... 1st Dec: 04hr, 00min In addition to the equatorial coordinates described in the notes above, astronomers also use (at least) two other coordinate systes: galactic coordinates and ecliptic coordinates. ... Ecliptic coordinates use the ecliptic (the Earth's path around the sun) as the equator, and are used for solar system work. ...

... Previous: The ACSIS Data Reduction System . ... The AST library supports the attachment of astrometric calibrations to astronomical datasets, the processing of this information, and generation of associated graphical output. ... In this paper we outline some more recent developments and applications, which include a set of efficient data re-gridding algorithms for curvilinear coordinate systems, improved FITS support, user-defined coordinate transformations, and pin-cushion/barrel distortion. ...
