Altitude intercept (a) the difference between hc and ho.
Watch time (w.t.) is the reading of your watch at the instant you make the sextant reading. The watch is set to the standard time of the time zone the boat is in.
Zone time (z.t.) is the correct time of the zone you're in.
Watch error (w.e.) is the amount of time the watch is slow (s) or fast (f). If the watch is slow, you add the error. If it's fast, subtract.
CHRONOMETER TIME (C.T.) what the chronometer reads, as set to GMT.
CHRONOMETER ERROR (C.E.) the amount of time it's slow or fast.
CORRECTED CHRONOMETER TIME (C.C.T.) the chronometer time corrected by adding slow C.E.'S and subtracting fast C.E.'S.
S.H.A. stands for sidereal hour angle. it is the angle westward from Aries to the star.
Azimuth Zn is the true bearing from the assumed position to the body and its G.P.
The local hour angle (LHA) is the distance the body (and its G.P.} is west of your position, measured in degrees.
LOCAL APPARENT NOON (LAN):The time when the sun and the vessel are on the same meridian.
