public struct CatEntry3
Inheritance
Object    ValueType    CatEntry3

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

Fields

Catalog 3-character catalogue designator.
Dec ICRS declination (degrees)
Parallax Parallax (milliarcseconds)
ProMoDec ICRS proper motion in declination (milliarcseconds/year)
ProMoRA ICRS proper motion in right ascension (milliarcseconds/year)
RA ICRS right ascension (hours)
RadialVelocity Radial velocity (km/s)
StarName Name of celestial object. (maximum 50 characters)
StarNumber Integer identifier assigned to object.
