void evaluationPerformed(int iterationsCount,
                         int evaluationsCount,
                         Orbit[] orbits,

                  throws OrekitException

Notification callback for the end of each evaluation.

Parameters:

iterationsCount - iterations count

evaluationsCount - evaluations count

orbits - current estimated orbits

estimatedOrbitalParameters - estimated orbital parameters

estimatedPropagatorParameters - estimated propagator parameters

estimatedMeasurementsParameters - estimated measurements parameters

evaluationsProvider - provider for measurements evaluations resulting from the current estimated orbit (this is an unmodifiable view of the current evaluations, its content is changed at each iteration)

lspEvaluation - current evaluation of the underlying least squares problem

Throws:

OrekitException - if some problem occurs (for example evaluationProviders not being able to provide an evaluation)
