LANSPECT Spectral Plot. The LANSPECT program uses the 4 electron energy channels and the 8 ion energy channels in each of the LEFS and LEMS detectors to make a four panel energy vs. time spectrogram. Figure 5.10 shows such a spectrogram made for an 8-hour period including the day 49, 1992, calibration. The LEFS electron spectra in the lower two panels do not respond to the calibration sources, as they should not, for they have no covers and no calibration sources. The upper two panels containing the spectra for the LEMS30 and LEMS120 telescopes show that the alphas from the Am source are measured in the upper channels, beginning about 2 hours after the cover closed command is sent, and ending about 30 minutes after the cover open command is sent. The cover close and open timings are examined in more detail in Section 5.2.5.
