| Starpm | — | Proper motion between two epochs |
| Fk5hip | — | FK5 orientation and spin with respect to Hipparcos |
| Fk52h | — | Transform FK5 star data into the Hipparcos frame |
| H2fk5 | — | Transform Hipparcos star data into the FK5 frame |
| Fk5hz | — | FK5 to Hipparcos assuming zero Hipparcos proper motion |
| Hfk5z | — | Hipparcos to FK5 assuming zero Hipparcos proper motion |
