Running QSO spectra using tplcombinationsolve simultaneously for both (refer to the attached param.json for more details):

  • galaxySolver,
  • qsoSolver,
  • using identical parameters for both solvers (no ism, no igm),
  • using the same templates, i.e., one meanQSO + 4 components,
    leads to differences in the pdf and the logEvidences.

while we can expect 50%-50% G/Q classification, we get 0%-100% or 11%-88% classification for a subset of spectra

  • I attach the list of the concerned SDSS QSO spectra
  • and the resulting .hdf5 file
