WHAT'S NEW Robert L. Park Friday, 6 Jan 06 Washington, DC DEEP SPACE CLIMATE OBSERVATORY KILLED. http://bobpark.physics.umd.edu/index.html -------------------- "After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance. I see that such intercourse long continued would make one thoroughly prosaic, hard, and coarse. But the longest intercourse with Nature, though in her rudest moods, does not thus harden and make coarse. A hard, sensible man whom we liken to a rock is indeed much harder than a rock. From hard, coarse, insensible men with whom I have no sympathy, I go to commune with the rocks, whose hearts are comparatively soft." - Henry David Thoreau, November 15, 1853 |

No, they are not centred and the quaternion clearly lacks of precision : the centre of the earth according to the quaternion is usually several dozens of pixels off-centre from the actual centre of the earth.
To get the json files for other dates, you just need to add the date in your query, e.g. http://epic.gsfc.nasa.gov/api/images.php?date=2016-1-12 My conclusion is that the provided quaternions are almost useless, I needed to recalculate my own. |

Have you tried contacting the EPIC team about what errors you are seeing in the quaternions?
