The best-fitting of observations is processed with multiple libraries of continuous UV-to-farIR spectral energy distributions (SEDs) with the help of the code Pegase.3 with dust (Fioc and Rocca-Volmerange, 2018, submitted to AA). The main results are: i) the IR excess is due to the Balmer break of red giant stars with galaxy ages of 450-500 Myrs ii) masses are high: 7 10^10 Msun for stellar mass, 10^11 Msun for galaxy mass, 3 10^8 Msun for d","authors_text":"A.
