Methodology based on Schureman 1924. Values computed May 2001.
(c) The location of the moon at Greenwich time t0 is different for an observer at some point O located
at longitude Lo than it is for the observer located at Greenwich. For each constituent, the observer is located
pL deg from Greenwich; therefore, the local equilibrium argument must be adjusted by -pL to account for the
difference in location between the point of interest (i.e., point O) and Greenwich.
(d) The -pL adjustment provides the necessary equilibrium argument correction for differences in
location between some point and Greenwich, i.e., a local equilibrium argument corresponding to an observer
at location O. However, the value of the equilibrium argument Greenwich (V0 + u) was specified with respect
to Greenwich t0. Therefore, Greenwich time must be written with respect to local time. Because local time
for the observer located west of Greenwich is earlier than local time in Greenwich (t0), the following
adjustment is made to convert local time to Greenwich time.
