For comparison to the new ion data, 1996 plots similar to the ones discussed below are available in the 1996. Plots of the 1996 data were created once a month from April through December 1996.
spectrograms contains plots for H+, He+, O+ and Stops. Stops contains the standard high time resolution spectrogram plots. H+, O+, and He+ have directories for two types of spectrograms. The high time resolution (esphtr) spectrograms have three panels with spin angle, energy, and polar angle on the vertical axis. In each panel, the data are averaged over the other two dimensions. The 2-D spectrograms (sepm) have a panel for each channel, energy on the vertical axis of each panel and spin angle / time on the horizontal axis. The times chosen for the plots are regions where higher counts are encounter. There is usually just one of these per orbit - just as Polar comes out of the radiation belt about two hours after perigee. Occasionally there are higher counts just before entering the radiation belt just after apogee. Each plot directory has a perigee subdirectory that contains plots of perigee passes for each orbit.
spectrogram/multi-ion contains high time resolution spectrogram plots with energy on the vertical axis in one file (ehtr) and spin angle (shtr) on the vertical axis in another file. The counts in the ehtr files are averaged over the spin angle and channel. In the shtr files, they are averaged over energy and channel. Each plot has three panels, one for each of the ions H+, O+, He+. These plots were created for the same time periods as the spectrograms discussed above.
spectrogram/direct-events contains spectrograms of counts as a function of TOF bin number and time for each channel. These plots were routinely created until 02/22/00 and occasionally after that. All of the existing direct-event spectrogram plot files are on the plot archive at either msfc-tide/archive or gsfc-tide/archive. They are in the po_tid_plt_yymm/spectrograms/direct-events subdirectory.
engspn-avg contains line plots of count rate versus time for each channel for a specific mass. There are plots for each mass in the H+, O+, He+, and Stops directories. In the filenames m0 is H+, m2 is He+, m3 is O+, and m4 is Stops. The counts are averaged over spin angle and energy and displayed in hertz. The 2006 ion data (H+, O+, and He+) are plotted with a different scale than Stops. The reason for this is that the count rate for the new ion data is so low that the standard range of 1-6 log hertz doesn't show anything. So for the ions, the range on the plot was changed to 0-6 hertz. The Stops (m4) plots were left at the 1-6 scale because the plots have been created routinely since 12/07/06 and the scales need to remain consistant. These plots were also created for H+ (m0) and Singles (m5) in 1996. All existing plots are on the archive at either msfc-tide/archive or gsfc-tide/archive. They are in the po_tid_plt_yymm/engspn_avg subdirectory.
strip-charts contains line plots of summed counts and counts in the TOF bins. PlotExplanation in the directory describes the two plots found in each PDF file.
masks contains surface plots of ion counts that are subtracted in order to remove background noise. The files with .stops. in the filename have the energy vs spin angle counts for the single channel that contains Stops counts. The other files contain the energy/spin angle/count surface plots for each ion (H+, O+, He+) for 4 channels, some of the plots have channels 1-4 and some have channels 4-7. Similar plots are also available once a month in tideteam/masks/mask_plots.
