Hello Robin and Antoine,

my result using a correction of Ho = Hs +10.0.32'
25/08/2013
Sun
Number of shoots = 14
LS Polynomial Fit:
H = a0 + a1 t + a2 t2
a0 = -701.701551
a1 = 90.646069
a2 = -2.700058
Mean Square Error:
mse = 0.000033
Maximun Altitude:
t (Hmax) = 16.785950 h = 16:47:09
Hmax = 59.088650 º
Meridian transit Position (James Wilson):
t MP = 16.788513 h = 16:47:19
COG = 0.0 º
SOG = 0.0 kt
Dec = 10.531486 º
GHA = 71.336503 º
H MP = 59.088632 º
B (MP) = 41.442854 º = N41º 26.57'
L (MP) = -71.336503 º = W071º 20.19'
Checks:
LHA = 0.000000 º Upper transit
Hc = 59.088632 º
Z = 180.000005 º Culmination = S
