 ``--<species>_merger.period``                The ouput periodicity of the plugin. A value of ``100`` would mean an output at simulation time step *0, 100, 200, ...*.
 											 
-``--<species>_merger.ratioOfDeletedParticles`` The ratio of particles to delete. The parameter have to be in Range *[0:1]*.
+``--<species>_merger.ratioDeletedParticles`` The ratio of particles to delete. The parameter have to be in Range *[0:1]*.
 
 ``--<species>_merger.maxParticlesToMerge``   Maximum number of macroparticles that can be merged into a single macroparticle.
