Add public, pure-double version of theoretical measurements
Observation models (e.g. AngularRaDec
) cannot at the moment be evaluated directly (need to go through a builder using the theoreticalEvaluation
method of AbstractMeasurement
, which systematically goes through a Jacobian matrix computation via automatic differentiation as implemented by the Gradient
class, causing a performance issue). This comes from the fact that the architecture is very much designed for orbit determination.
It would be nice to have a way to use observation models outside of the OD framework. This might impact modifiers.
