On this page we show a summary of the saturation limits of the JWST TSO modes. 



We show here information of where to find the bright limits of the JWST instrument modes that may be used for time series observations. 

Users should always refer to the JWST Exposure Time Calculator for the most up to date sensitivity and saturation limit predictions.
