 Aside from that, their priors remained unaltered except for the peak mean $\mu$.
 
 To provide a flexible solution to find double peak means across the whole time frame, the implementation of additional parameters proved indispensable.
-More precisely, the mean of both peaks or group mean was introduced as hyperprior \eqref{eq:PP mean of means} with a broad normal prior which enabled it to vary across the time frame as needed.
