Figure 4

Analysis of time-of-flight ladar data, in which the histogram bins have been converted to relative depth in meters. The first column shows the raw pixel data (in blue). The second column magnifies the plots of signal peaks in the first column. The third column shows the normalized cross-correlation values (blue curves) and the frequencies of positions (black bars) obtained from the MCMC samplers. The last column tracks the corresponding PSRF values against the number of samples. The final fit estimations (from MCMC) are the red curves in the first column.
