The IBEX-Lo Heavy Neutral Maps

By Jeewoo Park (jtl29@wildcats.unh.edu) & Harald Kucharek (herald.kucharek@unh.edu)

The IBEX-Lo heavy neutral maps are produced from the measured direct events identified as “Oxygen”, which are registered between 50 ns and 100 ns in TOF2; i.e. 50 ns ≤ TOF2 ≤ 100 ns (Park et al. 2015). Because there is no sputtering, Compton-Getting, and survival probability corrections, the “Oxygen” events may include O, Ne, and other heavier elements. The single O maps are produced by Pipeline code. If you inform us when you use this data, we would appreciate that. We also welcome any questions and suggestions.

1. single_ot_maps
There are six sets of the single IBEX-Lo heavy neutral maps observed from 2009 to 2011.
  - Six sets of maps for three consecutive years: map1–6
  - Four E-steps: E-step 5–8
  - Elements: counts, exposure times, count rates, standard deviations of count rates, S/N

2. combo_ot_maps (Fig. 1, 2, and 3 in Park et al. 2015)
There are three sets of the combined IBEX-Lo heavy neutral maps
  - comb-ot-m1m3m5: Combined odd maps  (map1 + map3 + map5)
  - comb-ot-m2m4m6: Combined even maps (map2 + map4 + map6)
  - comb-ot-m1m6: Combined all maps (map1 + map2 + map3 + map4 + map5 + map6)
  - Elements: exposure times, count rates, standard deviations of count rates, S/N

3. statistical_ot_maps (Fig. 4 and 5 in Park et al. 2015)
There are four sets of the statistical IBEX-Lo heavy neutral maps. Three statistical methods were applied to the combined all maps.
  - combo-ot-m1m6-snr: S/N-filtered maps
  - combo-ot-m1m6-clm: CLM maps
  - combo-ot-m1m6-snr-clm: S/N-filtered CLM maps
  - combo-ot-m1m6-cluster: Cluster maps
