Astronomy Library - Star Catalog Conversions
This is the index page for the Star Catalog Conversions section of the Astronomy Library for SOFA Library Issue 2021-01-25 for Fortran 77. 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 |
