SymDALI is a Mathematica implementation of DALI, utilizing symbolic differentiation. It is actively being developed for applications in gravitational waves.

An example of the application is show in this Figure. It is the Full Likelihood (red) vs DALI order 3 (blue). This event has SNR ~ 2000. 2 ET L-shaped detectors were used, one in Meuse-Rhine and another in Sardinia. The variables not present in the plot were kept fixed and the waveform is IMRPhenomD. More examples and applications are comming... (It is a lot of work).

At the moment this repository supports the calculation of DALI tensors to order 3 for IMRPhenomD. The file UserGuide.wl in Demo has some examples on how to use part of the functionality of the code. Right now It is fully functional only on MacOs Apple Silicon M1. I will also be implementing Linux and Windows as soon as possible. The code to generate the Figure will be coming soon.
