Chunk Subchunk structure in the AveragingTvi2 The averaging in is specified at construction time The	interval (i.e., the size of the chunk in time) is also specified at creation time

the interval must be an integer multiple of the averaging interval The input VI s setting must be compatible with those of the AveragingTvi2 This means that the chunk size of the input VI must have the same duration as the averaging VI Although the input VI and the averaging VI have the same the averaging VI will have fewer subchunks since N input subchunks will be averaged down to create a single output subchunk The input VI will also define the averaging boundaries by its definition of a chunk For if the input VI allows data with different scans to be in the same then they will potentially be averaged together The input VI must use the data description ID as a sort column so that a chunk will only contain data from a single DDID setting *void	originChunks (casacore::Bool forceRewind=false)
