IBEX-Lo Angular Histograms: Energetic Neutral Atom Counts per Orbit

Angular histograms of energetic neutral atom counts from the IBEX-Lo instrument. Each CSV file contains counts integrated over a full 8-day orbit for a single energy step and species category (hydrogen or oxygen/carbon). The data was produced by the National Aeronautics and Space Administration and was last updated on 2026-03 13.

Use Cases

• Analyzing the spatial distribution of hydrogen atoms based on 1-degree angular bands.
• Comparing count rates between hydrogen and oxygen/carbon species categories across different energy steps.
• Studying temporal variations in energetic neutral atom flux by comparing data from different 8-day orbits.
• Modeling heliospheric boundary properties based on angular count histograms.

Strengths

• Data is structured in 360 1-degree angular bands for detailed spatial analysis.
• Counts are integrated over full 8-day orbits, providing stable temporal baselines.
• Separate data for hydrogen and oxygen/carbon species categories allows for comparative studies.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
