because the
   data are coefficients of linear polynomials; as a set, they define a
   piecewise linear function that maps SCLK to the parallel time system.

   where --ss is the spacecraft ID code. The assigned values are triplets
   of SCLK values, corresponding parallel time values, and rates. The SCLK
   values are expressed in total ticks since clock start. The parallel time
   values may be expresse
