Wavelength range of the opacities go from 0.3-14 microns. Opacities are resampled to R=10,000 from an original R=1e6 LBL calculation performed by Richard Freedman and Roxana Lupu. Because it is resampled it should only be used for R~100 models. If higher resolution is needed, please contact one of the authors. You can use PICASO to explore using the Opacity Factor. import picaso.opacity_factory as opa molecules, pt_pairs = opa.molecular_avail(db_filename) print(molecules) ['Na','K','Li','Cs','Rb','CH4','CO','CO2','H2O','H2S','N2O','NH3','O2','O3','PH3','TiO','VO'] pt_pairs[0:10] [(1, 1e-06, 75.0), (2, 3e-06, 75.0), (3, 1e-05, 75.0), (4, 3e-05, 75.0), (5, 0.0001, 75.0), (6, 0.0003, 75.0), (7, 0.001, 75.0), (8, 0.003, 75.0), (9, 0.01, 75.0), (10, 0.03, 75.0)] As you can see from the pt_pairs, our grid is computed on a specific pressure-temperature grid that has a total of 1060 points. A full tutorial on querying the database is available in the PICASO read the docs. NOTE: A full table of references and citations is currently being compiled for publication with the Sonora Grid (Marley+2020 in prep). We have uploaded the opacities so that users can beta test with PICASO v2. We will include a full table of references here. If you publish with these opacities in the mean time, please contact one of the authors to get a full list of the proper citations.
