Notes: List of the AEDF tables. The number of rows in these tables depends on the temporal granularity of the informations they hold. The tables with a static content should have a small number of rows. The table with a fine temporal granularity means that they hold informations at a level at least as fine as the the time interval between two successive integrations. The majority of these tables are a legacy of the MSMv2. Some are said new although they were anticipated in the MSv2 document. Most of the MSMv2 tables had to be modified by adding attributes required for ALMA. Some tables are completely new. A few inter-relations between these tables have been modified (for example the Receiver table formely related to the Spectral-window table is now associated to the Feed table).
