*********** NMI GPS MONITORING SERVICE ************ Receiver frequency against NMI reference (x 10e-15), reported as 2-day linear fits (fit at MJD spans MJD-1 to MJD+1). Uncertainty shown for individual receivers is standard error of fit. Uncertainty shown for mean is max/min for receivers about mean.
