RDM is not designed to be a scientific instrument so that its capability is very limited. The sensor view is perpendicular to the Sun-pointing spin axis, and the spin period is 8 s. The sensor has a wide view angle. Although basic time resolution for particle measurements is 0.5 s, 16 s averaged data have enough counts to be statistically meaningful. Isotropic flux distributions should be assumed, and no pitch angle information is available. \nThe observations are summarized in [Takagi et al., 1993](https:\u002F\u002Fdoi.org\u002F10.1109\u002F23.273513) and [Nagai 2012](https:\u002F\u002Fdoi.org\u002F10.1029\u002F2012GM001281).\n\nThe data from the >2.5 MeV electron channel are open to the public since noise levels become high in the 0.3-0.95 and 0.95-2.5 MeV electron channels.\n\n### Data Format\n\n\u003Ctable summary=\"RDM Data Format\">\n\u003Ctr>\u003Cth>Column No.\u003C\u002Fth>\u003Cth>Name\u003C\u002Fth>\u003Cth>Unit\u003C\u002Fth>\u003Cth>Format\u003C\u002Fth>\u003Cth>\u003C\u002Fth>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>1\u003C\u002Ftd>\u003Ctd>Date\u003C\u002Ftd>\u003Ctd>YYYYMMDD\u003C\u002Ftd>\u003Ctd>i8\u003C\u002Ftd>\u003Ctd>date of observation\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>2\u003C\u002Ftd>\u003Ctd>Time\u003C\u002Ftd>\u003Ctd>HHMMSS (UT)\u003C\u002Ftd>\u003Ctd>1x,i6\u003C\u002Ftd>\u003Ctd>start time of each 16-s period\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>3\u003C\u002Ftd>\u003Ctd>L\u003C\u002Ftd>\u003Ctd>\u003C\u002Ftd>\u003Ctd>f7.2\u003C\u002Ftd>\u003Ctd>L value with the model geomagnetic field with the IGRF 2005\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>4\u003C\u002Ftd>\u003Ctd>INV\u003C\u002Ftd>\u003Ctd>deg.\u003C\u002Ftd>\u003Ctd>f6.2\u003C\u002Ftd>\u003Ctd>invariant latitude\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>5\u003C\u002Ftd>\u003Ctd>FMLAT\u003C\u002Ftd>\u003Ctd>deg.\u003C\u002Ftd>\u003Ctd>f7.2\u003C\u002Ftd>\u003Ctd>magnetic latitude of the S\u002FC footpoint\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>6\u003C\u002Ftd>\u003Ctd>MLAT\u003C\u002Ftd>\u003Ctd>deg.\u003C\u002Ftd>\u003Ctd>f7.2\u003C\u002Ftd>\u003Ctd>magnetic latitude\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>7\u003C\u002Ftd>\u003Ctd>MLT\u003C\u002Ftd>\u003Ctd>hours\u003C\u002Ftd>\u003Ctd>f6.2\u003C\u002Ftd>\u003Ctd>magnetic local time\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>8\u003C\u002Ftd>\u003Ctd>ALT\u003C\u002Ftd>\u003Ctd>km\u003C\u002Ftd>\u003Ctd>f9.2\u003C\u002Ftd>\u003Ctd>altitude\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>9\u003C\u002Ftd>\u003Ctd>GLAT\u003C\u002Ftd>\u003Ctd>deg.\u003C\u002Ftd>\u003Ctd>f7.2\u003C\u002Ftd>\u003Ctd>geographic latitude\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>10\u003C\u002Ftd>\u003Ctd>GLON\u003C\u002Ftd>\u003Ctd>deg.\u003C\u002Ftd>\u003Ctd>f7.2\u003C\u002Ftd>\u003Ctd>geographic longitude\u003C\u002Ftd>\u003C\u002Ftr>\n\u003Ctr>\u003Ctd>11\u003C\u002Ftd>\u003Ctd>FEIO\u003C\u002Ftd>\u003Ctd>1\u002F(cm\u003Csup>2\u003C\u002Fsup> s sr)\u003C\u002Ftd>\u003Ctd>e11.3\u003C\u002Ftd>\u003Ctd>electron integral energy flux (> 2.5MeV)\u003C\u002Ftd>\u003C\u002Ftr>\n\u003C\u002Ftable>\n\n## Data Analysis\nHere, you can find [a TDAS load procedure file for RDM data](http:\u002F\u002Flocalhost:28006\u002Fapp\u002Fstp\u002Fakebono\u002Fakb_load_rdm.pro). \nRDM data analysis becomes available on TDAS with this load procedure.
