Release 2.0

Major Changes

• Explicit Brown Dwarf tutorials
• Coupling to brand new python cloud code Virga!!
• Ability to specify wave range in opannection and ability to resample (consult your local theorist before doing this)
• Added "Opacity Factor" so that users can easiy query opacity data without going through SQL
• Removed opacity from git-lfs (was a bad system and users were having trouble)
• Fixed critical spherical integration bug and added more robust steps for 1d vs. 3d. Also added full tutorial to explain differences here.
• Added notebook for surface reflectivity

Functionality Expanded

Scientific functionality : thermal emission, 3d inputs

Major code structure changes:

Because thermal emission was added, we have changed the way the code output is returned:

w,a = case.spectrum()

is now..

df = case.spectrum()

where df is a dictionary with wavenumber, albedo, thermal, fpfs, full_output, pending what the calculation asked for.

All tutorials have been changed to reflect this!

In addition to thermal emission we also include more explicit tutorials for 3d calculations.

NOTE: we opted out of publishing a new paper for this release.

Small Bug Fixes

• astropy installation fix
• gravity fix with R and M inputs
• fixes for 3d input dev
