Figure 8

Scatter plot of MCMC samples for signal model parameters of a high-Q, high-f sine-Gaussian injection. The left panel shows the time-frequency plane with points colored by the wavelet phase parameter. Multiple modes and their phase-dependence are evident. The right panel shows the same chain samples, but now projected on the sky-location plane of the parameter space and colored by the time parameter. Here again it is plainly visible how different half-integer-period time shifts correspond to different “rings” on the sky, making this a challenging distribution to sample without well-tuned proposal distributions.
