      <description>Coefficients for piecewise linear prediction 
 of frequency of South Pole bin in receiver baseband output. Assumes 
 Clementine S-band carrier signal is fixed at 12500 Hz. Table gives 
 constant and linear terms for time segments of (usually) one second from 
 67001 to 67969 seconds on 9 April 1994 as seen at DSS 14. Predictions 
 were computed using Stanford program DF2SCM and results from earlier 
 calculations in programs BSRGEOM and BSRDOP. To find frequency F of 
 South Pole bin at time T, find the row for which T0 &amp;lt;= T &amp;lt; T1 and 
 compute F = F0 + DFDT*(T-T0).</description>
