The 1D pipeline computes the probability of a source to be a galaxy, a star or a QSO. The current data model provides redshift candidates for the type with the highest probability.
This story is related to a major update of 1D pipeline DM. The goal is to include to the DM all the candidates whatever the probability of a source to be a galaxy, star or qso.
We propose the following DM:
