07/03/03 48821 CTB Converted to XML format This relation specifies the LINEAR conversions which are to be applied to certain telemetry mnemonics. In the past PODPS used a wide relation: one which had a single tuple for each mnemonic, and 16 groups of fields specifying up to 16 conversion steps. Not only is this a poor design limit on the number of possible steps, but if a mnemonic only used 2 fields (a majority of cases) there would be a significant amount of unused space reserved in the database. The current design allows a mnemonic to have any number of tuples, each one of which only specifies a single conversion step. See OPR.29389. The set of conversion tuples (ordered by x_val) allows a stepwise linear conversion of any value between 0 and the last x_val. It is recommended that the last x_val be the maximum possible for the number of bits in the mnemonic. That is, if the mnemonic has 8 bits, the last x_val should be 255.
