Deming et al. 2013 spec Hubble Space Telescope satelliteWide Field Camera 328DEMING ET AL 2013 Observations used WFC3 with the G141 grism, providing wavelength coverage from 1.0 - to 1.7μm in first order. Each star was observed during a single visit comprising 5 consecutive orbits.
Evans et al. 2015 phot Spitzer Space Telescope satelliteIRAC8EVANS ET AL 2015 We have analysed ten primary transits and eleven secondary eclipses for HD209458b, made across all four IRAC channels.
Sing et al. 2016 spec Hubble Space Telescope satelliteSpace Telescope Imaging Spectrograph93SING ET AL 2016 We observed two transits of each target with the HST STIS G430L grating, and one with the STIS G750L. The G430L and G750L data sets contain typically 43 to 53 spectra, which span either four or five spacecraft orbits and were taken with a wide 52 x 2 arcsec slit to minimize slit light losses
Sing et al. 2016 spec Hubble Space Telescope satelliteWide Field Camera 329SING ET AL 2016 For the comparative study, we also included the WFC3 observation for HD 209458b (GO-12181, P.I. Deming)
Sing et al. 2016 phot Spitzer Space Telescope satelliteInfrared Array Camera (IRAC)2The eight targets in the large HSTsurvey were also all covered by Spitzer transit observations as part of an Exploration Science Programme obtained using IRAC instrument with the 3. and 4.5 channels in subarray mode.
