File Header 0 1640 7-Bit ASCII Text File header with production identification including spacecraft ID, DSN receiving antenna number, start time, stop time, file creation time, uplink band, and downlink band.

1-WAY Table Header 1640 328 7-Bit ASCII Text Header for 1-WAY Predict Table. Information includes tracking mode, start date and time, end date and time, and column headers for the data which follow.

MAVEN ROSE 1-WAY Frequency Prediction Coefficients 1968 335 Everett polynomial coefficients for 1-WAY frequency prediction. To calculate predicted frequency (Fp) at time t use the following equations: Fp(t) = (1-p)*f0 + g2*(1-p)*d20 + g4(1-p)*d40 + p*f1 + g2(p)*d21 + g4(p)*d41 where f0 and f1 are frequencies at consecutive times t0 and t1 in the table p = (t-t0)/(t1-t0) g2(x) = x*(x*x-1)/6 g4(x) = x*(x*x-1)*(x*x-4)/120 Carriage-Return Line-Feed 6 0 82 Time 1 1 ASCII_Time 12 UTC time at the DSN receiving station in hh:mm:ss.sss format Frequency 2 13 ASCII_Real 18 %18.4f Hz Predicted downlink frequency at Time d20 3 31 ASCII_Real 13 %13.3f Everett polynomial coefficient d20 d21 4 44 ASCII_Real 13 %13.3f Everett polynomial coefficient d21 d40 5 57 ASCII_Real 12 %12.2f Everett polynomial coefficient d40 d41 6 69 ASCII_Real 12 %12.2f Everett polynomial coefficient d41
