   I'm looking for general ways of calculating estimates of stationkeeping   
   deltavee requirements (e.g., m/(s y)) for satellites/stations in various   
   orbits (low, medium, high, and apostationary if relevnat) around   
   arbitrary bodies, and at each of the five Lagrange points between each   
   (sensible) combination of bodies.   
      
   Obviously this is something of a tall order, but for my purposes the   
   estimates need not be exact; within an order of magnitude or so is good   
   enough.  I managed to find e-folding instability times for a few   
   specific situations, but obviously 1. that doesn't answer the question   
   generally and 2. there's more to stationkeeping than just pure e-folding   
   time; there's also perturbations for nearby objects.   
      
   Could someone suggest a relatively simple algorithm to compute such   
   things to some reasonable degree of accuracy for each of the scenarios   
   described above?  Thanks.
