"In-depth analysis of schedules optimized for certain VLBI experiments using VieSched++";

Scheduling is an integral part of every Very Long Baseline Interferometry (VLBI)experiment and, at this stage, already determines the geometric stability of the final solution. Certainly, great care should be taken to create a high-quality schedule. Using a recently developed new VLBI scheduling software called VieSched++ together with other modules of VieVS thousands of schedules and millions of simulations were created and analyzed. This opens up the chance to investigate the connection between optimization criteria and parameters in scheduling with geodetic results gained from simulations. Here, we will present our results for optimizing schedules created by using VieSched++. We will show how combinations of different optimization criteria can be used to optimize VLBI schedules for a given network and scientific goal and how these criteria vary for different sessions. Furthermore, we will demonstrate the benefit of creating multiple schedules per session and selecting one of these schedules based on simulations. We will present an in-depth analysis of the created schedules and simulations, and come up with guidelines on how to create a good schedule.
