Request:  Correct formulae 
Comment:  GN7 Lambert Azimuthal Equal Area also corrected. (Remainder of probems are in transposition from GN7 to Access). 
Action:  In formula for method code 9805 (mercator), corrected "N = FN + a*k0* ln{tan(pi/4 + lat/2)[(1  esin(lat))(1 + esin(lat))]^e/2}" to "N = FN + a*k0* ln{tan(pi/4 + lat/2)[(1  esin(lat))/(1 + esin(lat))]^e/2}" (division sign missing).
In formula for methods code 9810 and 9829 (polar stereographic), corrected "E = FE rho * sin(lon – lonO)" to "E = FE + rho * sin(lon – lonO)" (addition sign missing).
In formula for methods code 9812 and 9815 (oblique mercator):
(i) corrected "H = F* t0*B" to "H = F*(t0)^B" (power instead of multiplication),
(ii) corrected "Q’ = e (B v ‘/ A)" to "Q’ = e^[ (B v ‘/ A)]" (power sign missing).
In formula for methods code 9810:
(i) corrected "ß = sin (q / qP)" and "ßO = sin (qO / qP)" to "ß = asin (q / qP)" and "ßO = asin (qO / qP)" (sin changed to asin);
(ii) corrected "D = a . [cos ?O / (1 – e2 sin2 ?O)0.5] / (Rq . cos ßO)" to "D = a . [cos latO / (1 – e2 sin2 latO)^0.5] / (Rq . cos ßO)" (? changed to lat and missing power sign inserted).
