Table 1: Characteristics of the five SDSS filters.
Table 2: The four astrophysical parameter (AP) ranges for each Hubble type in the regular library of PÉGASE synthetic spectra. Note that the AP ranges for each Hubble type partially overlap. The morphological type can be considered as an additional (but non-independent) parameter, required to fully explain the variance in the library. The final column (N) gives the number of spectra for each type (which sum to 888). See the regular library grid in Le Borgne & Rocca-Volmerange (2002) for comparison.
Table 3: The values of the parameters of the PÉGASE models which are kept constant in the library (Fioc & Rocca-Volmerange 1997).
Table 4: Galaxy classification with the SVM. The confusion matrix for the training set for galaxies at z=0. Columns indicate the true class, row the predicted ones.
Table 5: As Table 4 but for the test set.
Table 6: Summary of the performance of the SVM regression models for predicting the nine APs listed. The sample is for zero redshift but for interstellar extinction ( $A_{\rm V}$ ) varying from 0 to 10 mag. The second and third columns list the mean and RMS errors respectively. The final column gives the number of support vectors in the SVM model.
Table 7: Galaxy classification with the SVM. The confusion matrix for the training set for galaxies at z=0.0, 0.05, 0.1, 0.15, 0.2. Columns indicate the true class, row the predicted ones.
Table 8: As Table 7 but for the test set.
