was turned off. All the models have the same 72 layers from log $\tau_{Ross}$ = $-$6.875 to 2, where the step is log $\tau_{Ross}$ = 0.125. These parameters remained the same as @castelli01 for easy comparison.

All computations were performed on the Diodo cluster at the Instituto Astrofisico de Canarias. Diodo consists of 1 master node and 19 compute nodes, for a total of 80 cores and 256 GB of RAM, communicating through two independent Gigabit Ethernet networks. 16 of the compute nodes host 2 Intel Xeon 3.20 GHz EM64T processors each, with 4 GB of RAM (2GB per core); the remaining 3 compute nodes host each 16 Intel Xeon (E7340) 2.40 GHz EM64T processors, with 64 GB of RAM (4GB per core). On this cluster, about 3 months of computer time was required for ODF and model atmosphere calculations, using all 80 processors.

Calculation Method
------------------

Two separate scripts were developed, one for the ODF and Rosseland opacity calculations, and one for the ATLAS9 calculations. The ODF and Rosseland opacity calculations followed exactly the procedure described by @castelli01, and @castelli02 using the DFSYNTHE code for the ODF, KAPPA9 code for the Rosseland opacity, and ATLAS9 for the model atmopshere
