The most accurate result is when the Moon’s path (relative to the star background) is exactly towards or away from the other body. Astron ‘s Lunars page lists the direction of the Moon’s path, the direction of the selected body and (fairly arbitrary) alignment and overall quality indices. The User Notes chapter 18 gives more detail on this.
The Moon’s path can occasionally diverge up to 28 degrees from the ecliptic, so the ‘usual’ suspects such as Antares, Regulus, Spica and the planets do not always give the best alignment.

When I read about GMT of lunar altitudes. (I know not the most accurated method for determing GMT)
there is mentioned the moon must be near E or W bearing. But what is near? ± 5°, ±10°, ±15°.?
I can not find the bounderys . Pleace explain.
