Description

PyTDI is a Python package that provides a toolset to perform symbolical and numerical time-delay interferometry (TDI) calculations. It can be used to define arbitrary linear combination of time-shifted signals (i.e., combinations), symbolically handle these combinations, and numerically evaluate these combinations against data.

PyTDI also provides ready-to-use standard TDI combinations for the LISA mission.
