Fits to various values of temperature with iNNterpol with a bottleneck of 71 (CAE71-NN) for ATLAS9 data. For all values, log ɡ = 2.0. The test values not seen by the NN chosen randomly were used, that is why the metallicities are not exactly the same, but are all in an interval of ±0.25 dex. Predicted values are in dash-dotted lines, and we note that interpolation is in temperature and also in metallicities.
