How are data items converted from raw telemetry into physical units?
Data is converted from raw telemetry into physical units by the application of tables using specified table operators in a specified order. The IDFS keeps the decompression and scaling algorithms for each data set within the VIDF as a set of ASCII values in ASCII tables. Thus, one can easily update the scaling parameters within the VIDF by changing the VIDF as necessary. This process insures that any subsequent access of the data will be correctly converted to the set of physical units requested without the need to reprocess the entire data set. For ease of use, the procedure for applying tables to achieve different units is stored in the PIDF file.
