Astronomy Library - Ecliptic Coordinates
This is the index page for the Ecliptic Coordinates section of the Astronomy Library for SOFA Library Issue 2021-05-12 for Fortran 77. The Ecliptic Coordinates section includes the following routines:
| ECEQ06 | — | Ecliptic coordinates to ICRS RA,Dec, using IAU 2006 precession model |
| ECM06 | — | ICRS equatorial to ecliptic rotation matrix, IAU 2006 |
| EQEC06 | — | ICRS equatorial coordinates to ecliptic coordinates using IAU 2006 precession model |
| LTECEQ | — | Ecliptic coordinates to ICRS RA,Dec, using long-term precession model |
| LTECM | — | ICRS equatorial to ecliptic rotation matrix, long-term precession |
| LTEQEC | — | ICRS equatorial coordinates to ecliptic coordinates using long-term precession model |
