osculating to mean elements
It seems that there is an issue within the OsculatingToMeanElementsConverter class. I was getting some errors and after investigating a bit, here is where I see the problem:
Function "value", within QuadratureComputation class, accepts time offset (sec) as input. However, angular offset (rad) is given as inputs to "quadrature.solve".
