  Astronomy Library - Star Catalog Conversions

This is the index page for the Star Catalog Conversions section of the Astronomy Library for SOFA Library Issue 2021-05-12 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
