Abstract
We introduce the Fast Holographic Deconvolution method for analyzing interferometric radio data. Our new
method is an extension ofA-projection/software-holography/forwardmodeling analysis techniques and shares their
precision deconvolution and wide-field polarimetry, while being significantly faster than current implementations
that use full direction-dependent antenna gains. Using data from the MWA 32 antenna prototype, we demonstrate
the effectiveness and precision of our newalgorithm. Fast HolographicDeconvolutionmay be particularly important
for upcoming 21 cm cosmology observations of the Epoch of Reionization and Dark Energy where foreground
subtraction is intimately related to the precision of the data reduction
