| Euler 321 Yaw |
AngleUnit |
Real Number |
The first rotation (about the 3 axis, ie. Z axis)
in a 321 Euler sequence that rotates the ICRF frame into the J2000
frame. |
| Euler 321 Pitch |
AngleUnit |
Real Number |

Y axis) in a 321 Euler sequence that rotates the ICRF frame into
the J2000 frame. |
| Euler 321 Roll |
AngleUnit |
Real Number |
The third rotation (about the newest 1 axis, ie.
newest Z axis) in a 321 Euler sequence that rotates the ICRF frame
into the J2000 frame. |
