@janosch314 I never looked into the projection_solarorbit
function in detail, but it seems like it's only using the first component of LISA (I only see references to components[0]
), could that be related to the problem?
After updating the LISA noise model, I introduced a bug by not modifying line 447. It currently reads proj[in_band_slice, :] = doppler_to_strain * AET(polarizations[in_band_slice, :], eij, theta, ra, psi, components[0].L, ff)
but it should read proj[in_band_slice, :] = AET(polarizations[in_band_slice, :], eij, theta, ra, psi, components[0].L, ff)
The new sensitivity curves are from this paper.
They report some test cases: for example, the first row of Test Case 1 on page 31 is a BBH with source-frame individual masses of $10^5$, at $z=1$. The recovered SNR they find is something like 1100-1200.
The current implementation of the LISA sensitivity in GWFish overestimates this by roughly a factor 10:
The result is 12009.
