Wideband Mosaic Imaging and Pointing Corrections for the VLA Sky Survey

The Very Large Array Sky Survey (VLASS) critically depends on accurate wideband mosaicing algorithms for its single epoch imaging and ultimately cumulative imaging. To a large degree, VLASS requirements have driven CASA’s development of the AW-projection and related algorithms for widefield and wideband imaging in CASA. This Knowledgebase article provides complementary reports on the testing of Wideband Mosaic Imaging and Pointing Corrections for VLASS.
