T_XTIDE Tidal prediction

YOUT=T_XTIDE(STATION) makes a tidal prediction

for the current day using the harmonics file XTIDE. Predictions

at other times can be generated using [...]=T_XTIDE(STATION,TIM)

where TIM is a vector of matlab-format decimal days ( DATENUM).

If TIM is a scalar then it is taken as the number of days present

over which to make predictions. If TIM>1000 then it is taken to be

the starting time in matlab-format.

at the matlab time JD (UTC, but see code for details) where



tau = lunar time

　　s = mean longitude of the moon

　　h = mean longitude of the sun

　　p = mean longitude of the lunar perigee

　　np = negative of the longitude of the mean ascending node

　　pp = mean longitude of the perihelion (solar perigee)
