          "Description": "This data product contains Level 1 0.125-s values of solar \nwind magnetic field data taken by the IMPACT/Magnetometer on STEREO-A.  The interface \nat UCB provides access to CDF-formatted files of magnetic field data in RTN\ncoordinates.  The interface at UCLA allows selection of STEREO A or STEREO B \ndata and of vector quantities in RTN or spacecraft coordinates.  It also allows \nselection of either of two parameter sets: [Bx, By, Bz, |B|] or [RBx, RBy, RBz, |B|, \ncone and clock angles].  Further, this interface enables easy migration between \nplot vs. ASCII data presentation options and among the three available resolutions \n(1, 8, 32 Hz).  The parameter level information given below is specific to tyhe \nCDF version of the data at UCB.",
