Summary of the observed multiple systems in the Orion Nebula. We observed 16 multiple systems with a total number of 22 companion stars. The respective scales are indicated. The images of θ1 Ori B are from actual obervational data, except for the spectroscopic B1, B5 system, which is only a representation. The orbital positions for θ1 Ori D and θ1 Ori C are the positions obtained in this work and from the literature. All remaining close up depiction of stars (gray) are only for illustrative purposes and were not created with observational data. The background image of the Orion Nebula was created by ESO Igor Chekalin. The zoom of the Trapezium Cluster (θ1) is a cut from ESO M. McCaughrean et al. (AIP).
