Origins, Spectral Interpretation, Resource Identification, Security, Regolith Explorer (OSIRIS-REx): Altimetry Working Group Shape Model Bundle V1.0

This bundle collects the global and regional digital terrain models and associated spice data derived from the OSIRIS-REx Laser Altimeter (OLA) and Stereophotoclinometry (SPC) components. Several versions of the models are given, with models designated OLA generated from lidar data only, SPC generated from Stereophotoclinometry and those designated SPO generated from the combination of OLA and SPC. The model designated SPOv54 is to be used for ongoing scientific analysis. Other models were used at various points during the mission for both operational and publication purposes. The version numbers given in this archive correspond to version numbers given in various OSIRIS-REx scientific publications. USE SPOv54 FOR SCIENTIFIC ANALYSIS. Note that in the SPC derived DTM .FITS files, there is an error in the statistics planes. PLANE9 = 'Sigma ' PLANE10 = 'Quality ' SIGMA was supposed to be the standard deviation from the individual SPC maplets that went into making the DTM at that pixel. QUALITY was supposed to simply be the number of images that went into the SPC product at that pixel location. The values in these planes are nonsense, and should not be used. All other planes contain accurate values. This IS NOT a problem for OLA (data_derived_lidar_* collections) derived DTM .FITS files, which have good SIGMA and QUALITY planes.
