NICER Synthetic Data for Neutron Star Parameter Estimation

Three synthetic data sets generated for cross-verifying parameter estimation codes used in NICER X-ray astronomy analyses. The data simulates observations of millisecond pulsar PSR J0030+0451, including scenarios with ultra-compact stars and single or dual hot spots. The deposit includes auxiliary files and checksums, created by Slavko Bogdanov of Columbia University.

Use Cases

• Cross-verifying parameter estimation procedures based on synthetic X-ray pulse profiles.
• Testing models of neutron star mass-radius relations using simulated data.
• Validating analysis codes for single, uniform-temperature hot spot scenarios.
• Benchmarking inference methods for neutron stars with two distinct hot spots.
• Studying the effects of extreme compactness (R/M~3) on observational data.

Strengths

• Includes three distinct synthetic data sets covering specific astrophysical scenarios.
• Provides MD5 checksums for data integrity verification.
• Auxiliary files and a readme are included for each data set.

Limitations

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