  • Abstract
    The Fourier transform method is routinely used to find velocity distributions for the primary frequency standard NIST-7. The second-order Doppler shift is calculated from these distributions. Experimental and numerical tests of the method show that the shift can be determined within a few tenths of a per cent.
