Numbers of interpolated spectra are 2590 and 2125 for parallel plan models and spherical models, respectively.<br/>  <br/> Processing time is 8-9 sec per an interpolation on average. The time was improved from the 4D interpolation because used model templates were reduced from ~100-300 to ~30. <br/>  <br/> Processing time (sec)</p> <div class='table-wrap'> <table class='confluenceTable'><tbody> <tr> <th class='confluenceTh'> </th> <th class='confluenceTh'>mean</th> <th class='confluenceTh'>min</th> <th class='confluenceTh'>max</th> <th class='confluenceTh'>median</th> <th class='confluenceTh'>stddev</th> </tr> <tr> <th class='confluenceTh'>p-model</th> <td class='confluenceTd'>8.636729</td> <td class='confluenceTd'>8.308514</td> <td class='confluenceTd'>9.230231</td> <td class='confluenceTd'>8.643057</td> <td class='confluenceTd'>0.103503</td> </tr> <tr> <th class='confluenceTh'>s-model</th> <td class='confluenceTd'>8.295978</td> <td class='confluenceTd'>7.713312</td> <td class='confluenceTd'>10.262160</td> <td class='confluenceTd'>8.278359</td> <td class='confluenceTd'>0.218529</td> </tr> </tbody></table> </div> <p> <br/> The RMS of residuals is on average less than 1% but it becomes worse (&gt;1%) for the blue side of spherical models. <br/>  <br/> RMS (%)</p> <div class='table-wrap'> <table class='confluenceTable'><tbody> <tr> <th class='confluenceTh'> </th> <th class='confluenceTh'>mean</th> <th class='confluenceTh'>min</th> <th class='confluenceTh'>max</th> <th class='confluenceTh'>median</th> <th class='confluenceTh'>stddev</th> </tr> <tr> <th class='confluenceTh'>p-model all</th> <td class='confluenceTd'>0.049745</td> <td class='confluenceTd'>0.001470</td> <td class='confluenceTd'>1.144177</td> <td class='confluenceTd'>0.014773</td> <td class='confluenceTd'>0.103231</td> </tr> <tr> <th class='confluenceTh'>p-model blue</th> <td class='confluenceTd'>0.082114</td> <td class='confluenceTd'>0.001504</td> <td class='confluenceTd'>2.027684</td> <td class='confluenceTd'>0.023470</td> <td class='confluenceTd'>0.178944</td> </tr> <tr> <th class='confluenceTh'>p-model nir</th> <td class='confluenceTd'>0.019759</td> <td class='confluenceTd'>0.000869</td> <td class='confluenceTd'>0.377890</td> <td class='confluenceTd'>0.006437</td> <td class='confluenceTd'>0.037863</td> </tr> <tr> <th class='confluenceTh'>p-model red</th> <td class='confluenceTd'>0.025319</td> <td class='confluenceTd'>0.000738</td> <td class='confluenceTd'>0.473988</td> <td class='confluenceTd'>0.008091</td> <td class='confluenceTd'>0.049938</td> </tr> <tr> <th class='confluenceTh'>s-model all</th> <td class='confluenceTd'>0.769161</td> <td class='confluenceTd'>0.012876</td> <td class='confluenceTd'>21.199334</td> <td class='confluenceTd'>0.300931</td> <td class='confluenceTd'>1.726265</td> </tr> <tr> <th class='confluenceTh'>s-model blue</th> <td class='confluenceTd'>1.356829</td> <td class='confluenceTd'>0.024040</td> <td class='confluenceTd'>40.370744</td> <td class='confluenceTd'>0.509499</td> <td class='confluenceTd'>3.146068</td> </tr> <tr> <th class='confluenceTh'>s-model nir</th> <td class='confluenceTd'>0.260185</td> <td class='confluenceTd'>0.002558</td> <td class='confluenceTd'>4.715903</td> <td class='confluenceTd'>0.129480</td> <td class='confluenceTd'>0.436969</td> </tr> <tr> <th class='confluenceTh'>s-model red</th> <td class='confluenceTd'>0.340520</td> <td class='confluenceTd'>0.004064</td> <td class='confluenceTd'>6.427464</td> <td class='confluenceTd'>0.165988</td> <td class='confluenceTd'>0.596282</td> </tr> </tbody></table> </div> <p> </p> <p>The 2D interpolation has been done along two parameters of Teff and Log(g) at a fixed Z and <span class="error">&#91;alpha/Fe&#93;</span>.
