Figure caption: At left is a mock installation trial in the Mayall Garage. The FPD (black ring) is mounted on a steel A-frame with a height, inclination, and bolt interface matching the corrector barrel on the telescope (when mounted on the southeast work platform). At the right is an overview picture of the real installation, taken during the insertion of our third petal into the telescope. The installation is done with the telescope parked at the SE platform of the dome.

Figure caption: Left: 2016 August 1 HD 189733b transit lightcurve in ﹩u^{\prime} ﹩ = blue to ﹩i^{\prime} ﹩ = red, offset for clarity and uncorrected for stellar activity, with light gray curves representing each data set’s best-fit model. Corresponding residuals of the data to the model, with offsets for clarity, are shown below. The numerical values in the upper panel indicate the rms of each lightcurve fit in ppm. Numerical values in the lightcurve plot give the rms from the best-fitting model for each bandpass. Right: Each filter’s R  p /R * vs. wavelength of observation.

Figure caption: (a) Outlier nights of 2021 June 2 and 2021 June 22 corrected for unocculted spots using the Pont et al. (2013) prescription and a 2%, 5% and 10% occulted spot coverage fraction. An elevated occulted spot fraction of ≈ 5% – 10% would be required to match the Pont et al. (2013) data (cyan line), explaining the difference in R  p /R * for both nights. (b) Outlier nights of 2021 June 2 and 2021 June 22 corrected with the Pont et al. (2013) unocculted spot prescription and a 20%, 30%, and 40% bright region coverage fraction. We find that it takes a large (≈ 30% – 40%) and statistically unlikely bright spot coverage fraction to explain the underestimated radii for both nights.

Figure caption:  R  p /R * as a function of wavelength for our data, corrected using the Pont et al. (2013) 1.7% unocculted spot coverage prescription, and comparison data set of Pont et al. (2013) in cyan. Partial transits are indicated within the legend. Black x’s indicate the average R  p /R * value for each band. Our results are in excellent agreement with the Pont et al. (2013) data. We find real variation in the ﹩r^{\prime} ﹩ band that can be explained by varying spot coverage across the observation dates.

Figure caption:  R  p /R * as a function of wavelength with all nights normalized to the ﹩i^{\prime} ﹩ band to investigate bandpass-specific effects on the transmission spectra. Black x’s indicate the average R  p /R * value for each band. Pont et al. (2013) data is shown in cyan for reference. Having removed the effects of stellar activity to first order, we find no evidence of bandpass-specific variations.

Figure caption: Retrieved P–T profile (1σ region in red shaded region) for HR 8799 c using DS III. The data set (DS III) includes low- and high-resolution spectral data as well as photometric data. See Section 5.1 for more details for this data set and other data sets (DS I and DS II). The spectrally averaged contribution function is shown as the black solid line, which partially overlaps with a retrieved cloud layer (black dashed line). The pressure level of the retrieved cloud layer is consistent with that of a physical MgSiO3 cloud (blue dotted line).

Figure caption: Retrieved C and O abundances and C/O based on the PHOENIX spectrum. Top SDS I: low-resolution and photometric data only. C and O abundances from posterior samples (blue histograms) tend to be overestimated by 2.6–3.9σ when compared with the solar values (vertical dashed lines, Asplund et al. 2009). Vertical blue lines mark 16% and 84% percentile values of posterior distributions. Middle SDS II: High-resolution data plus CHARIS and photometric data. C/O is underestimated and C and O abundance uncertainties are the largest. Bottom SDS III: high and low-resolution along with photometric data. C and O abundances and C/O agree with the solar values within ∼1–2σ.

Figure caption: Haze generated spectral slopes as a function of the eddy diffusion coefficient and equilibrium temperature. Adapted from Ohno & Kawashima (2020), the solid and dashed lines show the slopes for haze mass flux of F = 10−12 and 10−13 g cm−2 s−1, respectively. The orange and gray lines denote the slopes for tholin and soot haze, respectively. The markers denote the slope retrieved by Welbanks et al. (2019; black circle) and our combined and unocculted starspot corrected data (black x), each with 1σ error bars and slightly offset for clarity.

Figure caption: Abundances assuming equilibrium chemistry (dashed lines) and a quenched pressure at 50 bar (the horizontal blue dashed line); 1σ ranges of retrieved abundances are shown in shaded regions. The retrieved abundances are inconsistent with the predicted values assuming equilibrium chemistry, at pressures between 0.1 and 1 bar, which is the peak of the contribution function (see Figure 4). Instead, the retrieved abundances are consistent with the predicted values assuming a perfect vertical mixing for pressures lower than 50 bar (vertical solid lines). This indicates a case of chemical disequilibrium and a quench pressure that is higher than ∼10 bar.
