An overall display of ELS data throughout orbit 2873 may be found in the file:

Files displaying blow-ups of all ELS sector data are found in the files:

Files displaying blow-ups of selected ELS sector data are found in the files:

Sector 3 blow-up to show photoelectron peak
The following is a time orientation summary of what is observed by ELS:
02:41 ELS data start in the solar wind
02:57 starting to pick up influence from Mars
03:07 beginning of bow shock
03:11 bow shock merges into the magnetosheath at about 100 eV
03:18 magnetosheath strength starts to decay in intensity and energy
03:35 magnetosheath energy decayed to ionospheric energies
03:36 plasma transition occurs, 10 eV electron intensity becomes dominate
03:36 photoelectron peaks observed
03:46 photoelectrons dissapear, break-up of organized low-energy plasma
03:52 higher energy plasma appears
03:54 low-energy burst appears (see note)
03:56 lower-energy burst dissappears, 10 eV plasma is observed
04:05:30 10 eV plasma begins to dissappear, less intense and disorganized
04:10:30 loss of low-energy plasma on sectors looking across the spacecraft
04:16:30 IMB is crossed and magnetosheath plasma is observed around 100 eV
04:46 Plasma looks sheath-like until end of data - never returns to the solar wind
following are interesting features to note in the ELS data:
03:36 There is a hint of an increase in the electrons, almost like a beam
03:54 low-energy burst is probably due to the spacecraft because the burst seems strongest in the sectors looking over the spacecraft

Additional Notes or Comments:
ELS data is seen to be in the 4-sec sweep mode through out this pass.
