2021 JULY: lte-codes-3.4.6 An interim upgrade fixing significant bugs in 3.4.5.

2020 JULY: lte-codes-3.4.5 An interim upgrade fixing some of the bugs in 3.4.0 and a significant upgrade to SterneOS -- version 4. This includes a new input interface, full implementation of an upgrade to the output model, including metadata, and better internal treatment of the chemical composition. I have not had time to implement the diffusion part of the code.

2019 NOVEMBER: lte-codes-3.4.2 A major upgrade is in preparation. This will have better provision for chemically stratified atmospheres including chemical diffusion by gravitational settling and radiative levitation.

2019 OCTOBER: lte-codes-3.4.0 A series of lectures on Stellar Atmospheres: the Analysis of Stellar Spectra was given in Kunming and Beijing 2019. Copies of the slides and some of the materials demonstrated in the lectures are placed online at the above link.
