      <description>Coefficients of best-fit linear segments
 describing frequency of the Clementine carrier signal in the original 
 25 kHz passband recorded at DSS 14. Microwave frequency was S-band. 
 First four numbers are C0, C1, C2, and C3; fifth and sixth numbers are
 times over which the coefficients are valid (T1 and T2). Frequency 
 f is evaluated f = C0 + C1*(t-T1) at time t; other two coefficients
 are not used.</description>
