SN 2017egm: Photometric and Spectroscopic Data Covering 380 Days

SN 2017egm is a superluminous supernova observed for about 380 days. Photometry was obtained from instruments including Swift UVOT and the Keck 10m telescope, while spectra were captured by facilities like the Lijiang 2.4m and Palomar 5m telescopes. This dataset, reported by WL Lin in 2023, compiles these multi-instrument observations.

Use Cases

• Modeling light curve evolution based on photometric time-series data
• Analyzing spectral features and chemical abundances from multi-telescope spectra
• Studying the progenitor and explosion mechanisms of superluminous supernovae
• Training models for supernova classification using combined photometric and spectroscopic signatures

Strengths

• Observations span about 380 days, providing a long-term temporal profile
• Data sourced from multiple high-caliber telescopes, including Keck 10m and Palomar 5m
• Combines both photometric and spectroscopic data for a multi-faceted view

Limitations

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