Looking for information needed to build a siege mapper

I used this web site in the past

https://www.moongatetravelers.org/index.php/encyclopedia-britannia/siege-mapper

but now it seems out of sync. I am hoping the information needed to build and synchronize a siege mapper is accessible somewhere.

 

Kinda of a yes and no answer as I'm not aware of a single place to get everything. Not really sure why or how the MGT page would be out of sync? It was pretty spot on before and the data hasn't changed at all. Can anyone else confirm that it's off?

As for the data to build your own.. you can dig most or all of it out of my NB Astronomy threads here on the forum in the Fire Lotus Tavern / Library sections. In particular, the Number Crunching thread will have a formula for finding the locations of the planets.. and others will have the orbit times.. I'd post links but it's late and I'm in the middle of something right now.. might do so later if needed but shouldn't be hard to find.. just search the Library for posts by me.

 

The web site seems to be in sync again.
