First Galactic Plane Survey: Radio Source Catalog at 8.35 and 14.35 GHz

The Galactic Plane survey covers a galactic latitude range of |b| < 5 degrees and a longitude range of -15 degrees < l < 255 degrees, representing 0.82 steradian (6.5%) of the sky. This table contains a source list of objects brighter than 0.9 Jy at 8.35 GHz and 2.5 Jy at 14.35 GHz, created by the NASA HEASARC in December 2004 based on CDS catalog data. Observations were conducted using the National Radio Astronomy Observatory-NASA Green Bank Earth Station.

Use Cases

• Detecting short-lived radio sources based on the survey's stated program goal.
• Analyzing source brightness and distribution across two specific radio frequencies mentioned in the description.
• Creating reference images of the Galactic plane based on the four combined observations described.

Strengths

• Covers a defined 0.82 steradian region of the sky, representing 6.5% of the celestial sphere.
• Provides source lists with specific brightness thresholds: >0.9 Jy at 8.35 GHz and >2.5 Jy at 14.35 GHz.
• Includes FITS format images, residual images, and archive data available online.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
