    John,

    Attached is a pdf of various formulas I have collected for doing CN calculations on a handheld calculator or in a spreadsheet, etc. Some are from navigation texts like the Nautical Almanac and Pub 229, some I got from Frank Reed, et al. and others are from random websites I've stumbled across over the years. These were intended as notes for my own personal use, so they might not be entirely clear and they are in no particular order. I thought that perhaps you [and others] might find them useful.

    Cheers!

    Sean C.
