COSMOS VLA 3GHz Catalog
The catalog contains sources selected down to a 5 sigma (sigma~2.3 uJy/beam) threshold. This catalog can be used for statistical analyses, accompanied with the corrections given in the data & catalog release paper (Smolcic et al. 2016). All completeness & bias corrections and source counts presented in Smolcic et al. (2016) were calculated using this sample. The total fraction of spurious sources in the COSMOS 2 sq.deg. is below 2.7% within this catalog. However, an increase of spurious sources (up to 24% at 5.0<S/N<5.5) is present (for details see Sec. 5.2., Fig. 16 and Tab 3 in the data & catalog release paper). A subsample with a minimal spurious source fraction can be selected by requiring a signal-to-noise ratio SNR # 5.5 (see Sec. 5.2., Fig. 16 and Tab 3 in the data & catalog release paper). The total fraction of spurious sources in the COSMOS 2 sq.deg. within such a selected sample is below 0.4%, and the fraction of spurious sources is below 3% even at the lowest SNR (=5.5).
