Spitzer Extragalactic First Look Survey: SDSS Spectroscopic Catalog

A spectroscopic catalog from the Spitzer Extragalactic First Look Survey, which aimed to characterize extragalactic sources observed in the mid-infrared. The survey comprises 4 square degrees of imaging from the Spitzer Space Telescope's MIPS and IRAC instruments, supported by ground-based optical and radio data. This specific catalog presents the SDSS spectroscopic information compiled by Papovich et al. in 2006.

Use Cases

• Characterize extragalactic source populations based on mid-infrared imaging down to sub-millijansky levels.
• Cross-match infrared sources with optical spectroscopic data from the SDSS.
• Analyze the properties of galaxies observed during the Spitzer Space Telescope's early science verification phase.

Strengths

• Data originates from the Spitzer Space Telescope, a major NASA observatory.
• Survey covers 4 square degrees of imaging with two instruments (MIPS and IRAC).
• 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.
• The underlying data collection concluded in 2003; newer surveys may offer more recent observations.
