  We revisited ten known exoplanetary systems using publicly available data
provided by the Transiting Exoplanet Survey Satellite (TESS). The sample
presented in this work consists of short period transiting exoplanets, with
inflated radii and large reported uncertainty on their planetary radii. The
precise determination of these values is crucial in order to develop accurate
evolutionary models and understand the inflation mechanisms of these systems.
Aiming to evaluate the planetary radius measurement, we made use of the
planet-to-star radii ratio, a quantity that can be measured during a transit
event. We fit the obtained transit light curves of each target with a
detrending model and a transit model. Furthermore, we used emcee, which is
based on a Markov chain Monte Carlo approach, to assess the best fit posterior
distributions of each system parameter of interest. We refined the planetary
radius of WASP-140 b by approximately 12%, and we derived a better precision on
its reported asymmetric radius uncertainty by approximately 86% and 67%. We
also refined the orbital parameters of WASP-120 b by 2$\sigma$. Moreover, using
the high-cadence TESS datasets, we were able to solve a discrepancy in the
literature, regarding the planetary radius of the exoplanet WASP-93 b. For all
the other exoplanets in our sample, even though there is a tentative trend that
planetary radii of (near-) grazing systems have been slightly overestimated in
the literature, the planetary radius estimation and the orbital parameters were
confirmed with independent observations from space, showing that TESS and
ground-based observations are overall in good agreement.
