DESCRIPTION                       = "Two spectral hygrometers were used
    simultaneously at Lunar Lake base camp.  Their serial numbers are
    SH015 and SH004. The spectral hygrometers provide the ratio Rsh =
    L(935)/L(880), where L(935) is irradiance at 935 nm and L(880) is
    the irradiance at 880 nm.  The measurement is acquired by aiming the
    optics at the sun and keeping the sun's image near the center of a
    ground-glass screen while the ratio is read from the display.  Note
    that 935 nm is in the middle of an atmospheric water band, whereas
    880 nm is not.  The principle of operation is that the greater the
    water vapor abundance, the lower the ratio."
