The present document was based on the ALMA Correlator Output Data Stream Description document [CODSD] (dated 2006-03-08) as a jumping-off point. In the process of creating the present specification, the ALMA document has been altered to meet the requirements of the EVLA project, and hence the present document should not be seen as a direct descendent of the ALMA document. Where appropriate, comments have been inserted into the present document to highlight and describe differences with the ALMA document for those readers familiar with that document. Nevertheless, the present document is meant to stand on its own as a self-contained and complete specification for the EVLA project. In addition, whereas the ALMA document specifies both the output in the binary data format and the output sent to ALMA's “data capture” subsystem, the present document addresses only the binary data format output.
