The attachment is part of an output from the USNO Celestial Navigation Data web page. Can anyone tell me how the USNO gets a parallax value of 15.6'? Every other source I tried got about 15.27', but 15.6' is the only one that makes the numbers agree with the Moon Altitude Correction Tables in the Nautical Almanac.
