ase explain

Hi -
Can some please explain what these numbers mean in an ASE file
Thanks

*CONTROL_ROT_SAMPLE 0 0.000 0.000 -1.000 0.785
*CONTROL_ROT_SAMPLE 160 -0.000 1.000 -0.000 0.090
*CONTROL_ROT_SAMPLE 320 -0.000 1.000 0.000 0.096
*CONTROL_ROT_SAMPLE 480 0.000 1.000 -0.000 0.101
*CONTROL_ROT_SAMPLE 640 -0.000 1.000 0.000 0.105

The first value is the timestamp, the second 3 are probably an axis of rotation, the last would be an angle in radians.
