Description
MWA observations simulated with the radio interferometry simulator pyuvsim are passed through the FHD-eppsilon analysis pipeline to verify behavior on known sky models. These simulations use a power spectrum that is logarithmically flat in power generated from sampling white Gaussian noise. We examine how the output power spectrum amplitude varies across frequency ranges, internal pipeline configurations, and between uvf and HEALPix cubes with respect to the ground truth. We additionally test if the ground truth power spectrum amplitude is recovered with the integration of multiple HEALPix cubes. This study is an external follow up of the analysis approach used by Line et al. (2024) to determine the MWA Phase I’s gridding density correction factor.
