Notes:

Data Files from Sing et al. (2016) are comma separated value (.csv), and contain wavelength in microns, wavelength half bin size in microns, planet-to-star radius ratio (Rpl/Rstar), and the 1-sigma error bar for Rpl/Rstar.

Model Files are ascii format (.txt), and contain wavelength in microns and the planet-to-star radius ratio (Rpl/Rstar).

The electronic version of the HD209458b transmission spectra as published in Sing et al. (2008)

The low res data runs from 300 to 770 nm and the medium res from 581 to 635 nm.  The data is binned by 16 and 18 points as in the published figure, though converted the spectra to Jupiter radii units using an adopted stellar radius of 1.125 R_sun.  The files contain columns of wavelength (angstroms), planet radii

(R_Jup), and planet radii error.  The 2016 update (Sing et al. 2016) is now the preferred version for the low resolution HD209458b optical spectrum.

Exoplanet Atmospheric Spectral Library

Here is the transmission spectra data from our Hubble Space Telescope programs (e.g. Sing et al. 2016).

If making use of these spectra, please cite the publication(s) listed.

1D models are also available with relevant citations listed in the file (e.g. Fortney et al. 2010).

WARNING:  If combining transmission spectra between datasets, in general there can be non-trivial vertical offsets due to differences in the system parameters (e.g. inclination, a/Rstar) and limb-darkening.  The data presented here has been reduced in a uniform manner to minimize such offsets, but caution is in order when comparing this data to any external datasets.
