Reflection Spectra Repository for Cool Giant Planets

<p>Supplementary&nbsp;material for&nbsp;<a href="http://iopscience.iop.org/article/10.3847/1538-4357/aabb05"><em>Exploring H2O Prominence in Reflection Spectra of Cool Giant Planets</em></a> - ApJ 858, 69 (2018).</p> <p>This repository contains 65520&nbsp;model reflection spectra&nbsp;of cool giant planets. The grid&nbsp;explores&nbsp;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:</p> <p>*m =&gt; 1-100 x solar (log(m) @ 0.0, 0.5, 1.0, 1.5, 1.7, 2.0&nbsp;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)</p> <p>(V 1.0, March&nbsp;30th&nbsp;2018):</p> <blockquote> <p>Initial&nbsp;release of the reflection spectra repository.&nbsp;</p> </blockquote> <p>(V 2.0, Oct&nbsp;1st 2019):&nbsp;</p> <blockquote> <p>The cool giant reflection spectra grid has been re-computed using the latest version of the PICASO albedo code (doi:&nbsp;<a href="https://arxiv.org/ct?url=https%3A%2F%2Fdx.doi.org%2F10.3847%2F1538-4357%2Fab1b51&amp;v=77076c4a">10.3847/1538-4357/ab1b51</a>). This fixes a few bugs&nbsp;and adds new model features (e.g.&nbsp;Raman scattering, see Batalha+2019).</p> <p>The new grid is packaged as a HDF5 file with an accompanying python script &#39;Open_Albedo_Database.py&#39;. The python script is provided to show&nbsp;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).</p> </blockquote> <p><strong>NEW</strong>:&nbsp;(V 2.1, Oct 3rd&nbsp;2019):&nbsp;</p> <blockquote> <p>Fixed a bug&nbsp;causing&nbsp;models with log(g) = 3.4 or&nbsp;3.9 to&nbsp;not display&nbsp;cloud opacity.</p> </blockquote>
