Hi Carl,
The vast majority of them are simply a vector of np.longdoubles (which are usually times or time differences) which are operated on by regular Numpy math functions to compute new quantities. For example, polynomial computations base on time, many trigonometric operations on the times for orbit calculations, things like that.
We don't really do big longdouble matrix operations.
Sounds like a good place to start looking for improvements is in addition and multiplication. Chuck
