Below can be found pdfs and contour plots for the inferred parameters (h_0, phi_0, psi and cosiota) of all 10 pulsars injected into the first 4 days of the S3 run. The best fit values (along with actual values for the public pulsars) are tabulated.

Below are the inferred values of h0 and phi0 for the 4 loudest injections (PSRs 3, 4, 8, 9). h0 and phi0 are shown being as they are the parameters furthest from the injected values.

Inferred values of h0 are found to be consistently lower than the injected values in H1 and consistently
higher in H2. Values of phi0 are consistent between the 2 IFOs, but not with that injected (see table
below).

We will be again testing our whole pipeline with simulated signals to check if any phase introduced during heterodyning and filtering.
