Well, when I consider if a lie is before me, then I ask myself what purpose would they have to try and deceive me. If there is no reason, they the nest question is whether or not their information is accurate to the level they claim.Digital resources like that abound. Some which will give me the exact degree that the sun is along the ecliptic -- instead of a display of the stars of the zodiac which it moves through.
But what if they are lying? How can I determine what that information is for myself??
