HerS: Herschel Stripe 82 Point Source Catalog for 79 Square Degrees

The Herschel Stripe 82 Survey (HerS) point source catalog contains 32,815 sources detected at 250 microns, with 13,300 and 3,276 sources at 350 and 500 microns, respectively. Observations were taken by the SPIRE instrument on the Herschel Space Observatory, covering 79 square degrees along the SDSS Stripe 82 region. The catalog was produced by the National Aeronautics and Space Administration to study correlations with the dark matter density field.

Use Cases

• Measure galaxy bias and redshift distribution based on infrared intensities mentioned in the description.
• Cross-correlate infrared sources with external tracers (radio to X-ray galaxies, clusters, lensing) as described.
• Analyze source completeness and false detection rates based on the stated 50% completeness and <1% false rate.
• Study the properties of point sources removed due to extended nature, based on the 24 removed extended sources.

Strengths

• Covers a significant 79 square degree area along the well-studied SDSS Stripe 82.
• Contains 32,815 sources at 250 microns with defined signal-to-noise (>3 sigma) and quality criteria.
• Provides depth estimates of 13.0, 12.9, and 14.8 mJy beam⁻¹ at 250, 350, and 500 microns, respectively.
• Quantifies expected false positive rate as 1.2 +/- 0.2 deg⁻², allowing for error estimation.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown for the full band-merged catalog, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
