Note: source model atmospheres are available upon request.
For spectroscopic fitting 3D corrections should be added for accurate atmospheric parameters. For photometric fitting 1D models are sufficient but please check the 3D grid and reference below for UV photometry. The link below provides 3D correction functions in Fortran and IDL.
