Query: Generalized elimination of the global translation from explicitly
  correlated Gaussian functions   This paper presents the multi-channel generalization of the center-of-mass
kinetic energy elimination approach [Mol. Phys., 111 2086 (2013)] when the
Schr\"odinger equation is solved variationally with explicitly correlated
Gaussian functions. The approach has immediate relevance in many-particle
systems which are handled without the Born--Oppenheimer approximation and can
be employed also for Dirac-type Hamiltonians. The practical realization and
numerical properties of solving the Schr\"odinger equation in laboratory-frame
Cartesian coordinates are demonstrated for the ground rovibronic state of the
H$_2^+=\lbrace\text{p}^+,\text{p}^+,\text{e}^+\rbrace$ ion and the
H$_2=\lbrace\text{p}^+,\text{p}^+,\text{e}^+,\text{e}^+\rbrace$ molecule.
