public struct CatEntry3

The CatEntry3 type exposes the following members.

Fields
 NameDescription
Public fieldCatalog 3-character catalogue designator.
Public fieldDec ICRS declination (degrees)
Public fieldParallax Parallax (milliarcseconds)
Public fieldProMoDec ICRS proper motion in declination (milliarcseconds/year)
Public fieldProMoRA ICRS proper motion in right ascension (milliarcseconds/year)
Public fieldRA ICRS right ascension (hours)
Public fieldRadialVelocity Radial velocity (km/s)
Public fieldStarName Name of celestial object. (maximum 50 characters)
Public fieldStarNumber Integer identifier assigned to object.

Remarks
Basic astrometric data for any celestial object located outside the solar system; the catalogue data for a star.

This structure is identical to the NOVAS2 CatEntry structure expect that, for some reason, the StarName and Catalogue fields have been swapped in the NOVAS3 structure.

Please note that some units have changed from those used in NOVAS2 as follows:

  • proper motion in right ascension: from seconds per century to milliarcseconds per year
  • proper motion in declination: from arc seconds per century to milliarcseconds per year
  • parallax: from arc seconds to milliarcseconds
