Process/System for Deciding on Natural System Cycle Times

Primary Goal would be to find a place that has the most accurate information and use that one.   Would need to have ALL of our needed cycles.

More realistically we would look at each cycle and date individually, and apply a few steps to determine what the most accurate time is, or take an average of the most accurate times.

Overall Agree to Use Nasa's SKYCAL (even if it may not be correct??? is there any what to know???) Eventually evolve to using a averaged approached, but that is MUCH more work.

When we don't have an exact match from NASA, we can do a Cross Reference Match from CalSky.com & In-the-Sky.org.  If they are different by just a few minutes, then average them.  If they are 1 minute off, then take the one that is earliest, or average towards the one that is earliest.  If they are hours off, then go to the averaging method.

System for Averaging:
If there is only one calculated time available, then we just use it.
IF there are between 2-4 we take all of them and average them together, unless there is a obvious accurate location we agree to focus on, or if it is obvious that one of the times is probability not correct.
If there are 5 or more, then we remove the two furthest times, and average the three closest times.

When in doubt, choose the time that is earlier.

Most Likley Accurate (can use one website, but should continue to research):


Cross Reverence:

CalSky.com
http://www.calsky.com/cs.cgi (click on Long Table of Contents and click "Phenomena for each planet)
Has almost everything.

In-The-Sky.org

Mercury & Venus Ellipse A&Ps, plus lots of other stuff
Possibly other Planets as well :) Goes to 2029

Cross Reference Cycles for CalSky and IntheSky.org:
    Murcurry A&P
    Venus A&P
    Mars A&P
