Abstract:
In the context of the VLA-COSMOS Deep project, additional VLA A array
observations at 1.4GHz were obtained for the central degree of the
COSMOS field and combined with the existing data from the VLA-COSMOS
Large project. A newly constructed Deep mosaic with a resolution of
2.5" was used to search for sources down to 4σ with
1σ∼12uJy/beam in the central 50'x50'. This new catalog is
combined with the catalog from the Large project (obtained at
1.5"x1.4" resolution) to construct a new Joint catalog. All sources
listed in the new Joint catalog have peak flux densities of ≥5σ
at 1.5" and/or 2.5" resolution to account for the fact that a
significant fraction of sources at these low flux levels are expected
to be slightly resolved at 1.5" resolution. All properties listed in
the Joint catalog, such as peak flux density, integrated flux density,
and source size, are determined in the 2.5" resolution Deep image. In
addition, the Joint catalog contains 43 newly identified
multi-component sources.
Description:
The central seven pointings of the mosaic for the VLA-COSMOS Large
project (pointing numbers: F07, F08, F11, F12, F13, F16, F17) were
observed using the VLA A configuration in 2006 February and March.
The observations were executed on 11 days.
