The purpose of the mission was to make pioneering measurements of the interplanetary medium from the vicinity of the Earth's orbit to 0.3 AU. (The planet Mercury is at 0.4 AU.)Data coverage for selected parameters for this data set is: interplanetary magnetic field (1976-01-18 - 1980-03-04), solar wind plasma (1976-01-18 - 1980-03-04), and spacecraft trajectory coordinates (1976-01-18 - 1980-03-04).Magnetic field data were provided by Prof. F. Mariani, Istituto di Fisica G. Marconi, Rome, Italy; Plasma data - by Dr. R. Schwenn, Max-Planck-Institut fur Aeronomie, Lindau, Germany.Time Coverage of merged files: January 1, 1976 - March 4, 1980.Helios-2 data have been reprocessed to ensure a uniformity of content and coordinate systems relative to data from other deep-space missions:All spacecraft trajectory data were transformed to a Heliographic Inertial (HGI) coordinate system.Magnetic field components were transformed to RTN system.Trajectory data, interplanetary magnetic field data, and plasma data were merged into individual hourly records.Data gaps were filled with dummy numbers for the missing hours or entire days to make all files of equal length. The character '9' is used to fill all fields for missing data according to their format, e.g. ' 9999.9' for a field with the FORTRAN format F7.1. Note that format F7.1 below really means (1X,F6.1),etc. <_Description>Source: Master/CDFglobalAttributes/TEXT <_Rights> SPDX Creative Commons Zero v1.0 Universal https://spdx.org/licenses/CC0-1.0.html https://spdx.org/licenses/ https://omniweb.gsfc.nasa.gov/coho/html/cw_data.html Documentation COHO dataset <_Note>URL also in all.xml.
