Apologies The second post was an itchy trigger finger. The first and third posts rushed out before a meeting. I feared I was too hasty thinking about it in transit. Returning home, I found all but the below was pure gibberish as I managed to get caught in my own circular argument. While there is a high correlation between the first value returned from R-to-P and cosine of Hc, they are not nearly close enough for any meaningful use in navigation. Back to the drawing board.
