The data are in ASCII format and cover the time period\nfrom 12/26/1972 to 8/9/1973. The four different files provided in this\ndata set contain the data for He, O2, N2, and Ar, respectively. Each data\nrecord provides date, time, density, density error, altitude, latitude and\nlongitude, and local solar time. \n",
