Pioneer 11: Daily Ultraviolet Photometer Cruise Data from 1973

Daily averages of spin-averaged ultraviolet photometer readings from the Pioneer 11 spacecraft, starting April 6, 1973. The data were collected by NASA's Pioneer 11 mission to measure backscattered solar Lyman alpha and Helium line emissions. These measurements are used to study solar wind interactions with the interstellar medium.

Use Cases

• Modeling solar wind interaction with the interstellar medium based on ultraviolet intensity measurements.
• Analyzing temporal variations in backscattered solar Lyman alpha emission at 1216 A.
• Studying spatial variations in solar Helium line emission at 584 A.
• Correlating Pioneer 11 cruise data with other heliospheric datasets.

Strengths

• Data originates from the authoritative NASA Pioneer 11 mission.
• Provides daily averaged measurements starting from a specific date (April 6, 1973).
• Focuses on two specific ultraviolet spectral lines (1216 A and 584 A) for targeted analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in a BIN format, which may require specialized tools for access.
