Astronomy Library - Star Catalog Conversions
This is the index page for the Star Catalog Conversions section of the Astronomy Library for SOFA Library Issue 2023-10-11 for ANSI C. The Star Catalog Conversions section includes the following routines:
| Fk425 | — | Convert B1950.0 FK4 star catalog data to J2000.0 FK5 |
| Fk45z | — | Convert a B1950.0 FK4 star position to J2000.0 FK5, assuming zero proper motion in the FK5 system |
| Fk524 | — | Convert J2000.0 FK5 star catalog data to B1950.0 FK4 |
| Fk52h | — | Transform FK5 star data into the Hipparcos frame |
| Fk54z | — | Convert a J2000.0 FK5 star position to B1950.0 FK4, assuming zero proper motion in FK5 system and zero parallax |
| Fk5hip | — | FK5 orientation and spin with respect to Hipparcos |
| Fk5hz | — | FK5 to Hipparcos assuming zero Hipparcos proper motion |
| H2fk5 | — | Transform Hipparcos star data into the FK5 frame |
| Hfk5z | — | Hipparcos to FK5 assuming zero Hipparcos proper motion |
