Reflection Spectra Repository for Cool Giant Planets

Supplementary material for <em>Exploring H2O Prominence in Reflection Spectra of Cool Giant Planets</em> - ApJ 858, 69 (2018). This repository contains 65520 model reflection spectra of cool giant planets. The grid explores the influence of metallicity, gravity, effective temperature, and sedimentation efficiency on H₂O absorption signatures in giant planet atmospheres. We also include two animations to visualise how the prominence of H₂O absorption evolves over this parameter space. The included models range over: *m =&gt; 1-100 x solar (log(m) @ 0.0, 0.5, 1.0, 1.5, 1.7, 2.0 dex) &lt;-- log(m) = 1.7 new for V2 of the database.<br> *g =&gt; 1-100 m/s² (evenly over log(g) in steps of 0.1 dex)<br> *T_eff =&gt; 150-400 K (linearly in steps of 10 K)<br> *f_sed =&gt; 1-10 (linearly in steps of 1) (V 1.0, March 30th 2018): Initial release of the reflection spectra repository. (V 2.0, Oct 1st 2019): The cool giant reflection spectra grid has been re-computed using the latest version of the PICASO albedo code (doi: 10.3847/1538-4357/ab1b51). This fixes a few bugs and adds new model features (e.g. Raman scattering, see Batalha+2019). The new grid is packaged as a HDF5 file with an accompanying python script 'Open_Albedo_Database.py'. The python script is provided to show how to open the albedo database, plot the spectra, and save spectra as a .txt file. The user need only change 4 lines (specifying log(m), log(g), T_eff, f_sed) and run the python script to produce a plot of the albedo spectra (both with and without H₂O absorption). <strong>NEW</strong>: (V 2.1, Oct 3rd 2019): Fixed a bug causing models with log(g) = 3.4 or 3.9 to not display cloud opacity.
