Kirkwood 1000y sim
01/02/13 at 09:46:27
 
An "old" file in a new jacket .  
I once received from EDG a file kirkwood1000y.txt to output it with the Gsim viewer , but I don't know anymore to which system setup this file belongs . Maybe EDG ca help ?  
But nevertheless . I've added to the viewer a new functionality which colorcodes individual particles at the start of the sim .  
Example of output is hereunder : it seems that especially the violet particles , which are originally at the right end of the picture tend to get unstable . The sim was run for 1000 years .  
If one is interested to get the new viewer feature I can  post it .

Same sim as above , but now with the evolution of the Sma of the individual particles as function of time .  
One can see some volet particles escape to lower Sma after a couple of years .

I'll have to rummage through my files and remember what I was doing (and how to do it), but I'll take a look!

I couldn't find anything resembling that unfortunately. The graph might be from somewhere in the kirkwood gaps experimental threads, but I couldn't find a source gsim file for it.

I had a thought... instead of colouring your particles by starting distance, can you colour them by time?  
 
IIRC one problem with your graphing method is that if a particle gets flicked out once to some extreme value, it stays on the graph as a red dot. But if you could colour the particles based on time somehow... so maybe they start off as red when they first enter a region of 'phase space' on the graph and then 'cool' over time if they don't stay there (going through orange, yellow, green, etc to violet) then that will provide us with visual information showing whether the particle really is stable in that region or if it just entered it once.  
 
Something like that anyway - I'm not sure if what i suggested specifically would work, but it might give you an idea maybe?
