Implemented retention of unused photons associated with the same geolocation segment pulse ID and major frame ID across ATL13 segments/transects; Implemented exclusion of TEP photon events when forming ATL13 short segments; Implemented computation of water surface spectral moments and spectral width; Fixed errors related to the identification of photons necessary to define valid crests and upcrossings; Updated source code to compute electromagnetic bias as positive; Filtered geolocation segments whose composite POD/PPD flag is non-zero; Updated weak beam interpolation of ATL09 strong beam atmospheric profile source data to align with along-track segment; Added short segment fractions of near and full saturation; Added DEM height & source at the short segment rate; The ATL03 EGM2008 geoid is now reported in the tide free system; Implemented computation of height adjustment to apply to the apparent surface height; The first photon bias correction and mean height adjustment estimated from deconvolution are now applied to the observed apparent surface height when computing orthometric heights and heights referenced to the WGS-84 ellipsoid; Implemented updates to ATL13 short segment along-track water body surface slope to include spacecraft velocity; Implemented exclusion of very long segments associated with insufficient photon counts within the range of subsurface fit from contributing to the exponential fit to the observed histogram; Made anomalous short-segment information available in a subgroup populated with output parameters; Implemented ingestion of ATL03 quality_ph and computation of short segment photon counts designated at each quality level as a rank 2 array; The short segment anomaly testing now includes all anomaly tests; Added anomalous short segment averaged coordinates and length based on endpoint locations with the anom_ssegs subgroup.
