Monthly Notices of the Royal Astronomical Society, 491(1), 1127–11451365-2966https://doi.org/10.1093/mnras/stz2954http://hdl.handle.net/10566/5918This is the first of a series of papers based on sensitive 610 MHz observations of the ELAIS N1 field, using the Giant Metrewave Radio Telescope. We describe the observations, processing and source catalogue extraction from a deep image with area of 1.86 deg2 and minimum noise of ∼7.1 μJy beam−1. We compile a catalogue of 4290 sources with flux densities in the range of 28.9 μJy– 0.503 Jy and derive the Euclidean-normalized differential source counts for sources with flux densities brighter than 35.5μJy⁠.enGalaxies: activeInfrared: galaxiesRadio continuum: galaxiesELAIS N1 fieldRadio frequenciesArticle
