Hello,
I have the Apollo 15 X-ray spectrometer trans-earth coast data file,
which has the following ephemeris/auxiliary data available:
* Time (GMT)
* Time (GET)
* Apolune/perilune altitude (nautical miles)
* Vehicle look angle to the moon (alpha, beta)
* Vehicle attitude with respect to local horizontal coordinate system
(pitch, yaw, roll)
* Geodetic altitude (nautical miles)
* Sun look angle in the sun vector system
* Sun look angle relative to the stable system
* Vehicle look angle to the Sun (alpha, beta)
Any help on the exact definitions (and/or how to calculate them) of the
above quoted values are appreciated, especially "Vehicle look angle",
"local horizontal coordinate system", "Sun look angle in the sun vector
system" and "Sun look angle relative to the stable system".
Thank you,
Best regards,
Erik Kuulkers
