IHW Comet Halley Photometric Magnitudes, V2.0

Photometric magnitude measurements of comet 1P/Halley submitted to the International Halley Watch Photometry and Polarimetry Network. Both broadband and narrowband magnitudes are included, with filter parameters for each measurement. This second version includes corrections to known errata and a combined chronological table.

Use Cases

• Analyze comet brightness trends based on photometric magnitude measurements
• Compare broadband and narrowband filter observations based on included filter parameters
• Study comet 1P/Halley's photometric behavior based on chronological data
• Validate or correct photometric models based on known errata corrections

Strengths

• Data includes both broadband and narrowband photometric magnitudes
• Known errata have been corrected in this second version
• A combined chronological table of all measurements has been added

Limitations

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