SNDATA_ROOT: Supernova Analysis Software Environment

SNANA software's environment bundles public light curve data, filter transmissions, and simulation models. It includes primary SEDs, calibration files, and libraries for SNIa and core-collapse supernova simulations. The environment is maintained by R. Keßler at the University of Chicago.

Use Cases

• Simulating supernova light curves based on included SNIa and core-collapse models.
• Calibrating astronomical observations using the provided filter transmission data.
• Analyzing public supernova light curve data sets within a standardized software environment.
• Generating synthetic surveys using the included cadence and host-galaxy libraries.

Strengths

• Includes multiple data types: light curves, filter transmissions, SEDs, calibration files, and simulation models.
• Specifically contains models for both Type Ia (SNIa) and core-collapse (CC) supernovae.
• Provides libraries for simulation cadence and host-galaxy properties.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
