The luni-solar corrections are considered under the three following aspects:

Quality of results: the application of tidal corrections to all stations is pointless as long as the operations do not substantially exceed two hours.

Working conditions: it seems possible to increase the duration of programs without any loss of precision, but operating in such a way requires particular care.

Behaviour of gravity meters: the introduction of tidal corrections allows to separate three kinds of instrumental drifts; a good knowledge of the mean operational drift enables to appreciate the quality of a given set of measurements.

An example is given to show the possibility in some cases to detect small errors which are close to the limit of precision of the instrument.
