Claim Text:
1. A method of adjusting speed and/or routing of at least a part of a movement plan of a table under an immersion fluid supply system of a lithographic apparatus, the method comprising: determining, for a certain discrete movement of a plurality of discrete movements of the movement plan, a value of one or more parameters characterizing a risk of a bubble of a size greater than a certain non-zero size being present in immersion fluid through which a patterned beam of the lithographic apparatus will pass by determining that a position, at which immersion fluid leaked from the immersion fluid supply system is present, travels under immersion fluid contained by the immersion fluid supply system and by determining that a position, at which immersion fluid leaked from the immersion fluid supply system is present, does not travel under immersion fluid contained by the immersion fluid supply system; and based on the value of the one or more parameters, adjusting (i) the speed and/or routing of a part of the movement plan corresponding to a discrete movement earlier than a discrete movement for which the risk of a bubble is determined, and/or (ii) the speed and/or routing of a part of the movement plan corresponding to a discrete movement for which the risk of a bubble is determined.
