Imaging performance of candidate Long Wavelength Array stations for the J-ARGUS multistatic system

The J-ARGUS project will combine two independent Long Wavelength Array (LWA) stations with the Jicamarca Radio Observatory (JRO), forming a new multistatic system for low-frequency radio studies in Peru. Here, we present a comparative assessment of candidate antenna distributions for the proposed LWA stations, focusing on their visibility coverage and imaging response. We simulate uv-coverage patterns, derive the corresponding point spread functions, and study the influence of different visibility weighting schemes on image reconstruction over the 10 - 88 MHz range. This analysis is used to characterize the expected performance of each layout for radioastronomical observations, especially the imaging of bright southern-sky sources. We also discuss the relevance of these sources for future calibration and commissioning. Overall, the results provide an initial quantitative evaluation of the proposed LWA configurations within the broader scientific context of J-ARGUS.
