%X The present article proposes a partial answer to the explicit inversion of the tensor tomography problem in two dimensions, by proving injectivity over certain kinds of tensors and providing reconstruction formulas for them. These tensors are symmetric differentials of any order as well as other types obtained after taking their transverse covariant derivative once. Such reconstruction formulas require introducing additional types of fiberwise Hilbert transforms which satisfy a convenient generalization of the Pestov-Uhlmann commutator formula \cite{Pestov2005}. Numerical simulations in {\tt MatLab} are provided using the author's code presented in \cite{Monard2013}, justifying the exactness of the formulas in some cases of simple and near-simple metrics, and displaying issues encountered as one increases either curvature, lack of simplicity, or tensor order, in all of which cases the formulas derived in the first part become theoretically insufficient.
