  "description": "Best-avail second data in the coordinate system of measurement of the data ('native'), provided by Vassouras, Brazil (VSS) observatory. The units and labels that apply for the parameters depend on this orientation. For example, if the native coordinate system is X, Y, Z then the labels are X, Y, Z and units nT, nT, nT. Note that the coordinate system of measurements of data provided by the observatory may change in the time interval indicated by startDate/stopDate. A parameter called 'vectorComponents' is available for this data set which describes the data's coordinate system. Data are also available in a single coordinate system over the full time interval of available data; these datasets have ids with 'xyzf', 'hdzf', and 'diff' in place of 'native'.
