An optimized scheduler for radial velocity measurements at Telescopio Nazionale Galileo

In this paper, we introduce the scheduler for Radial Velocity (RV) measurements at the TNG telescope which is currently under development. The scheduler is a web-based application designed to optimize RV observations for GAPS community science projects. Additionally, it will be made available to all other follow-up RV programs that wish to benefit from it. We will detail the process of inputting, prioritizing, and selecting targets for observation with HARPS-N and GIANO-B at the TNG, while ensuring appropriate allocation, respecting the timing and constraint, among all the programs that use this scheduler to optimize their measurements. This fully automated software will be able to flank the observer with a night-by-night ordered list of optimal targets, as well as optimal backups in case observing conditions change, enabling users to adapt to rapid changes due to weather conditions that require a swift response, without compromising the optimization process, ensuring high-quality observations. We foresee to provide the scheduler with a web-based panel that interrogates the underlying application programming interfaces to load/reload/edit the calculated OBs list and export them for execution by the telescope operator.
