Dataset 'REC' Size: 3x3x13585 MaxSize: 3x3xInf Datatype: H5T_IEEE_F32LE (single) ChunkSize: 1x1x3397 Filters: deflate(4) Description: Rectangular coordinates (X,Y,Z) in km. Dataset 'UT' Size: 3x13585 MaxSize: 3xInf Datatype: H5T_STRING String Length: 26 Padding: H5T_STR_NULLPAD Character Set: H5T_CSET_ASCII Character Type: H5T_C_S1 ChunkSize: 1x850 Filters: deflate(4) Description: UT time. It includes 3 different UT times, which match three crossing positions for each position in ABB_MSO (and in all other coordinate sets) as described in Hall et al., 2016. In summary, the middle measurement and time is the one used as the crossing, the first timestamp is a some threshold before (see Hall et al., 2016), the third some threshold after (see Hall et al., 2016).
