As long as people are asking about the term ECEF, I would like to fix 
the definition of ECEF on the Wikipedia page


but first I want to make sure I'm not wrong. Since every high-school 
student in the world relies on Wikipedia, it would be good for it to 
be close to right.

The definition says "The z-axis is defined as being parallel to the 
earth rotational axes, pointing towards north". Isn't it actually 
coincident with the rotational axis, rather than being parallel?

I just created a discussion page under the definition so the world at 
large could comment.
