Calibration and Imaging Pipeline Processing Baseline-dependent Averaged Visibilities

In this paper, we present a calibration and imaging pipeline whose processing functions directly operate on visibilities to which Baseline-Dependent Averaging (BDA) has been applied. This avoids the need to expand BDA-ed visibilties to full resolution. We demonstrate that this reduces the computational needs for calibration (both visibility prediction and solving) and (de)gridding by processing fewer visibilities without causing unexpected degradation of the results. This first prototype of a BDA-enabled calibration and imaging pipeline allows further exploration of BDA-enabled processing, for which we raise several questions.
