Paper abstract: Gen TSO is a noise calculator specifically tailored to simulate James WebbSpace Telescope (JWST) time-series observations of exoplanets. Gen TSO enablesthe estimation of signal-to-noise ratios (S/N) for transit or eclipse depthsthrough an interactive graphical interface, similar to the JWST Exposure TimeCalculator (ETC). This interface leverages the ETC by combining its noisesimulator, Pandeia, with additional exoplanet resources from the NASA ExoplanetArchive, the Gaia DR3 catalog of stellar sources, and the TrExoLiSTS databaseof JWST programs. The initial release of Gen TSO allows users to calculate S/Nsfor all JWST instruments for the spectroscopic time-series modes available asof the Cycle 4 GO call. Additionally, Gen TSO allows users to simulate targetacquisition on the science targets or, when needed, on nearby stellar targetswithin the visit splitting distance. This article presents an overview of GenTSO and its main functionalities. Gen TSO has been designed to provide both anintuitive graphical interface and a modular API to access the resourcesmentioned above, facilitating planing and simulation of JWST exoplanettime-series observations. Gen TSO is available for installation via the PythonPackage Index and its documentation can be found atpcubillos.github.io/gen_tso.
