The readout time between exposures is only 14 ms. Optical multi-wavelength observations though the z', i', r' and g' filters were performed on separated night.
Benneke et al. 2019 spec Hubble Space Telescope satelliteSpace Telescope Imaging Spectrograph8We obtained time-series spectroscopy of six transits using HST, including three from 1.1 microns to 1.7 microns using Wide Field Camera 3 (WFC3) and three at optical wavelengths (0.55–1.0) usingthe Space Telescope Imaging Spectrograph (STIS). We complement these HST transit observations with a total six Spitzer/IRAC transit observations as well as a total of 20secondary eclipse observations at 3.6 and 4.5 (Figure 2 and 3)

Ehrenreich et al. 2014 spec Hubble Space Telescope satelliteWide Field Camera 3107EHRENREICH ET AL 2014 The observations are grism slitless spectroscopy. They consist in series of exposures taken with the G141 grism of WFC3 infrared channel (WFC3/IR) in stare mode. The grism provides a spectral coverage of 1.1 to 1.7 microns, including the 1.38m band of water with a resolution of 300. WFC3/IR exposures are obtained in MULTIACCUM mode, i.e. they are built from multiple non-destructive readouts of the Teledyne HgCdTe detector. Our starting point for the analysis is the flat-fielded(FLT) images produced by CALWF3, the WFC3 pipeline. The analysis follows the steps described in the paper https://arxiv.org/pdf/1405.1056.pdf
