Run 8 ('4d'-Var)
2 sec of observations (in 5 sec run). Observations are of both angles, but not their speeds. This is as run 3, but some observations have been removed (between 1.5 and 2 seconds).Graph A: Primary angle of double pendulum vs time
Key:Green points mark the assimilation cycle boundaries.
Blue is the exact solution.
Red are the observations used.
Magenta is the assimilated solution using the set of observations from run 3.
Light green is the assimilated solution using the modified set of observations.
