File: CRRES_Orbit_Survey.txt This survey of the CRRES orbits and energetic electron activity for each orbit was provided by Al Vampola from the file SURVEY.txt provided with his 0.5-sec MEA electron data set in directory particle_mea/500ms_pcbinary/. 9/23/2004 J. F. Cooper ------------------------------------------------------------------------------------------------------------------- Source: SURVEY.txt Author: Al Vampola The notes in this file are the result of a cursory examination of the 1-minute averaged datasurvey plots. The plots are available on another disc of this data set. They are presented as XLC files which can be plotted and manipulated by EXCEL Ver. 4.0 or later. The numerical data which were used to generate the .XLC files are available as ASCII text files on the same disc. * Special interest orbit TDI -- Temporally-dispersed injection TDD -- Temporally-dispersed dropout ORBIT DATE YR DOY START STOP NOTES 0 7/25/90 90 206 71280 106980 MEA Off 1 7/26/90 90 207 20400 56040 MEA Off 2 7/26/90 90 207 55860 91560 MEA Off 3 7/27/90 90 208 4980 40680 MEA Off 4 7/27/90 90 208 40500 76140 MEA Off 5 7/27/90 90 208 75960 111660 MEA Off 6 7/28/90 90 209 25080 60780 Very soft spectrum @ apogee, flat background ~2cps * 7 7/28/90 90 209 60600 96300 Very disturbed.
