Spitzer Extragalactic First Look Survey: WIYN/Hydra Spectroscopic Catalog

A spectroscopic catalog from the Spitzer Extragalactic First Look Survey, which aimed to characterize mid-infrared source populations. The survey comprises 4 square degrees of imaging and 67 hours of observation time from the Spitzer Space Telescope. Data was compiled by the National Aeronautics and Space Administration and the catalog presents WIYN/Hydra spectra as described in Marleau et al. (2007).

Use Cases

• Characterizing extragalactic source populations based on mid-infrared observations.
• Analyzing spectroscopic data from ground-based optical telescopes like WIYN/Hydra.
• Cross-referencing mid-infrared imaging with ancillary optical and radio telescope data.

Strengths

• Covers 4 square degrees of imaging centered at J1718+5930.
• Based on 67 hours of observation time from the Spitzer Space Telescope.
• Includes ancillary data from ground-based optical and radio telescopes.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• File formats include BIN, which may require specialized tools to access.
