  "x_description": "The Geospace Region and Magnetospheric Boundary identification (GRMB) dataset contains the label of the region in which C1 is travelling. It results from visual selection of the boundary in the pregenerated plots Each record indicates the time interval passed in a GRMB region (the exit time of this region is the next entry time). The label is described as a string and as number (1 to 15). It comes along with quality factors. Meanings of location_code and location_label variables: 1,  IN/UKN:   Inside the magnetosphere 2,  IN/PLS:   Plasmasphere 3,  IN/PPTR:  Plasmapause Transition Region 4,  IN/PSH:   Plasmasheet 5,  IN/PSTR:  Plasmasheet Transition Region 6,  IN/LOB:   Lobe 7,  IN/POL:   Polar Regions 8,  IN/MP:    Magnetopause 9,  IN/MPTR:  Magnetopause Transition Region 10, OUT/MSH:  Magnetosheath 11, OUT/BSTR: Bow Shock Transition Region 12, OUT/SWF:  Solar Wind and Foreshock 13, OUT/UKN:  Outside the magnetosphere 14, UNKNOWN:  Available data are not conclusive 15, N/A:      No data  Since this information has been generated by visual inspection of existing plots (with a pixel resolution down to 7s), the change of a region is not resolved with a constant time resolution. See the caveats and the user guide for more information.  inbound_vs_outbound variable has been generated automatically and it is related to the way the region identified by location_label is crossed (inbound or outbound). It is applicable for the following GRMB items: PPTR, POL (distant part only), MP, MPTR, MSH, BSTR 0: Not Applicable for this item 1: This is an inbound crossing 2: This is an outbound crossing 3: Bound cannot be identified  crossing_complexity variable has been attributed by the operator at the selection. Default value is one (simple crossing). In a complex crossing, the region properties are not fully matching the typical location_label item properties.  1: This is simple region/boundary 2: This is a complex region/boundary  quality_location_code has been generated automatically and it is related to the number of prime products displayed to the operator at the item start time. Each GRMB item has 3 to 5 prime products. The more these products are available , the more certain is the region identification. See the user guide for detailed prime products. 0 (bad): no prime products were available. 1 (low): a single prime products was available. 2 (fair): more than one prime product was available and more than one was missing. 3 (good): all but one prime products were available. 4 (top): all prime products were available.  quality_location_label has been generated automatically and it is related to the available dataset displayed to the operator at the entry start time. It is a 32-chars long string. This combined 16 product codes (each is a 2-char long string) displayed at the selection time. See the user guide for detailed information and the CSA product of each code. This variable is intended to be checked in case of a suspicious label.
