| contents | The up-coming Vera Rubin Observatory's Legacy Survey of Space and Time (LSST) opens a new opportunity to rapidly survey the southern Sky at optical wavelenghts (\ie ugrizy bands). In this study, we aim to test the possibility of using LSST observations to constrain the mass and velocity of different KN ejecta components from the observation of a combined set of light curves from GRB afterglows and KNæ. We used a sample of simulated light curves from the aforementioned events as they would have been seen during the LSST survey to study how observing strategies' choice impacts the parameters' estimation. We found that the observing strategy design to be the best compromise between light curves coverage, observed filters and fit reliability involves a high number of visits with long gap pairs of about 4 hours every 2 nights in the same or different filters. The features of the observing strategy will allow us to recognize the different stages of the light curve evolution and gather observations in at least 3 filters. |
