In [the original version of Adriaan] (https://github.com/NLeSC/enram/blob/master/doc/vol2bird-adriaans-version-20140716/vol2birdprof_h5.c) these outliers were included, mainly because in some (rare) mixed rain/bird migration cases quite a large fraction of gates can be marked as \"outlier\" (the velocity model is only appropriate for describing the movement of a single flow component, not for a mixture of two components).\r\n\r\nWe need to validate whether the current implementation causes any major differences in calculated bird densities or not.\r\n"}}
