AMI Galactic Plane Survey 16-GHz Source Catalog
Listed in NASA Data Portal
The Arcminute Microkelvin Imager (AMI) Galactic Plane Survey is a large-area survey of the outer Galactic plane to provide arcminute resolution (approximately 3 arcminutes) images at milli-Jansky (mJy) sensitivity in the centimeter-wave band.
Description
This table contains results from the first data release of the survey, consisting of 868 deg<sup>2</sup> of the Galactic plane, covering the area above 40 degrees Declination (corresponding to 76 to 170 degrees Galactic Longitude) between Galactic Latitudes of -5 to +5 degrees at a central frequency of 15.75 GHz (1.9 cm).
The noise level in the survey is <~ 3mJy/beam away from bright sources. This table contains the source catalog of 3503 radio sources detected with peak flux densities at or greater than 5 sigma. In their paper, the authors describe in detail the drift-scan observations which have been used to construct the maps, including the techniques used for observing, mapping and source extraction, and summarize the properties of the finalized data sets.

These observations constitute the most sensitive Galactic plane survey of large extent at centimeter-wave frequencies greater than 1.4 GHz. This table was originally ingested by the HEASARC in March 2013 based on the <a href="cdsarc.cds.unistra.fr/ftp/cats/J/MNRAS/429/3330">CDS Catalog J/MNRAS/429/3330</a> file catdr1.dat. It was updated in September 2013 using the latest data file from the CDS, which provided positions with improved precision.
