This PR introduces significant changes to the way that data and PSDs are handled. It includes a new
datasub package that introducesDataandPowerSpectrumclasses.The
Dataclass stores data in the time domain, with functionality to obtain FD representations with different windows as needed; theDataclass can also retrieve strain online from GWOSC, and produce Welch estimates of the PSD (returning aPowerSpectrumobject). Future data manipulation tools (e.g., reading in GW frames) should be added to this class.The
PowerSpectrumclass includes utilities to draw simulated data, as well as interpolating to a given frequency grid.The likelihood has been modified slightly to interact with these new objects.
I have checked the
GW150914_IMRPhenomPV2.pyexample. Let me know which other examples should be working and I'll push further updates to this PR.
