## GW190412 ## GW190412
A similar plot for the GW190412 event (top 5 [PE samples](https://git.ligo.org/pe/O3/S190412m/-/blob/master/Preferred/dat/M4-PhenomHM_pesummary.dat)) is given below, and we see that in this case, the plateau occurs once we use the top-350 eigenvectors to approximate the covariance matrix. In this case, the Frobenius norm of the residuals is 3.5e-10.
