	SimpleFreeFieldHRSOS version 1.1 represents a development stage towards standardized convention set from AES69-2025.		SimpleFreeFieldHRSOS version 1.1 represents a development stage towards standardized convention set from AES69-2025.

	As compared to version 1.0, version 1.1 updates the datatype such that the size of dimension R is defined by the corresponding size of Data.IR.		As compared to version 1.0, version 1.1 updates the datatype such that the size of dimension R is defined by the corresponding size of Data.IR. ReceiverPosition must have the dimension RCI.
