    Nice find, Allen.
    On pages 4 and 5, the authors reported better atmospheric transmission at 1064 nm than at 532 nm,
    and also noted, "Furthermore, 1064 nm is not visible to the naked eye; it is not likely to disturb
    neighboring households and is potentially more covert." They went on to point out that detector
    gains would be significantly lower, which might require amplification of the signal. They also
    mentioned the better transmission and covertness of 1064 nm in the executive summary and in their
    conclusions, but did not make a recommendation.
    The orbit they describe definitely is NOSS.
