phd0 and prob_of_exist

[leoneto98]

Im using your repository for the Radar Rs408 and I have notice that the prob_of_exist is attributed at pdh0, as show below: https://github.com/Project-MANAS/ars_40X/blob/506ebaa6d120ed2e96b31f1c6212dfe132c16a2b/src/ros/cluster_list_ros.cpp#L54 I would like to know why this attribution is made? the pdh0 is not the probability for being an artefact caused by multipath or similar? The association between pdh0 and prob_of_exist is direct? Thanks for the great repository, Léo
