1. A lithographic projection apparatus comprising:
- a support structure configured to hold a patterning device, the patterning device configured to pattern a beam of radiation according to a desired pattern;
a substrate table configured to hold a substrate;
a projection system configured to project the patterned beam onto a target portion of the substrate;
a liquid supply system configured to provide a liquid, through which the beam is to be projected, in a space between the projection system and the substrate; and
a controller configured to control application to the projection system of a force related to a weight transfer attributable to a member of the liquid supply system.
