GAMA-23 deep field with uGMRT Band-2: source catalogue and source count

We present the low-frequency GAMA-23 field of the Galaxy and Mass Assembly (GAMA) survey with upgraded Giant Meterwave Radio Telescope (uGMRT) observations in Band-2 ($120-250$ MHz). The on-source observation was conducted for ~5 hours. The final image achieved an off-source RMS noise of 320 $μ$Jy beam⁻¹, covering an area of 5.86\,deg² with restoring beam size of 15.4''×8.2'' at the central frequency of 183 MHz. The catalogue derived from the radio image includes 569 sources with a flux density limit of ≥\,5σ. The flux density measurements and the positional accuracy are cross-verified and compared with other radio catalogues available in the literature. The spectral indices derived from fitting a power law are -0.68+0.18-0.23 for the ASKAP EMU catalogue and -0.72+0.19-0.24 for the NVSS catalogue. The normalised source count derived from this catalogue is consistent with models and observations with a nominal catalogue threshold of 1.7 mJy, while the sensitivity varies across the image.
