NIRCam Imaging Mosaics for NEXUS Deep Epochs:
This directory contains NIRCam imaging mosaics and corresponding uncertainty maps for the NEXUS-JWST Deep Epochs in the F200W and F444W filters. These products are part of the NEXUS quick data release (Zhuang et al. 2026).

Data Reduction & Methodology:
These images were reduced following the procedures described in NEXUS early data release paper (https://ui.adsabs.harvard.edu/abs/2026ApJS..282...54Z/abstract) and are sampled at a pixel scale of 30 mas. For the F444W filter, we provide an additional version at 60 mas pixel scale (*_60mas_*.fits). This version is optimized to mitigate sub-sampling artifacts and "pixelated" PSF shapes arising from the limited two-point dither pattern used during acquisition. 

Data Structure:
Both science data (*_data.fits) and uncertainty maps (*_error.fits) store the image array directly in the 0th extension (Primary HDU).
