00readme.txt for Photoelectron fluxes (JPEG images and data in Excel spreadsheet) Directory contents: These directory contains data from the Photo-Electron Spectrometer (PES) that flew on the Atmosphere Explorer E (AE-E) satellite. These data were provided by P. Richards (U. Alabama Huntsville) who had received them from the PES PI J. Doering (JHU) around 1982. The data were submitted in graphical form showing photoelectron flux spectra for different altitudes and solar zenith angles for the uplegs and downlegs of 2 AE-E orbits. These graphs are special as they constitute the only accurate source for the final and officially sanctioned AE-E PES data. Less detailed data plots and more information on the instrument can be found in the papers listed below. The graphs are provided in three different image formats (JPG, gs.JPG, TIFF) (CAUTION: The small dots connected by lines are the actual data. Please ignore any other symbols or lines). filename: yyddd_ooox_pes_aee.ppp yy=year, ddd=day-of-year, ooo=orbit-number, x=u/d upleg/downleg, ppp=jpg or tif files: 75361_458d_pes_aee.jpg 75361_458d_pes_aee_gs.jpg 75361_458d_pes_aee.tif 75361_458u_pes_aee.jpg 75361_458u_pes_aee_gs.jpg 75361_458u_pes_aee.tif 75363_483d_pes_aee.jpg 75363_483d_pes_aee_gs.jpg 75363_483d_pes_aee.tif 75363_483u_pes_aee.jpg 75363_483u_pes_aee_gs.jpg 75363_483u_pes_aee.tif Perigee was just north of the equator during this period We are greatly indebted to our 2006 summer high school intern, William Chin, who manually scaled these graphs and entered the fluxes values into EXCEL spreadsheets.
