The data are at each resolution for several mutually exclusive, contiguous hours during most days. The field-plasma-merged data set was created at GSFC/Space Physics Data Facility (SPDF) as part of the LunaSOX effort, from CDAWeb data sets THC_L2_ESA (good quality, high angular resolution mode only) and THC_L2_FGM. Geocentric spacecraft and moon orbit data from SSCWeb were used to add geocentric and selenocentric spacecraft position data to the merged data set records.", "Acknowledgement": "Please acknowledge
