    • The method of stacking power spectra has been used by radio astronomers in deep searches for millisecond pulsars, although all corrections were applied to the data stream via resampling and not sliding the spectra. For more information on the implementation, see S. B. Anderson, Ph.D. thesis, California Institute of Technology, 1993

    • It may seem that the optimal duration of data to analyze is equal to the amount of data taken by the instrument. This is not neccessarily true for a given algorithm (e.g. the stack-slide search or the two-stage hierarchical search). Suppose, under the stated assumptions, we determine the optimal amount of data (Formula presented) to analyze using a given algorithm. Now, hold the computational resources fixed, but increase the amount of data by a factor of (Formula presented), so that we have (Formula presented) times as long to analyze it. Unfortunately the computational cost increases by more than a factor of (Formula presented) because the number of parameter-space corrections increases faster than (Formula presented) Thus, we cannot complete our analysis in the time it takes to acquire the data. Implications of this point are further discussed in Sec. VIII

    • The average expected power loss for a source randomly placed within a cubical patch is (Formula presented). In paper I we quoted an average that was computed for ellipsoidal patches; this is not appropriate to the cubical grid that will likely be used in a real search
