A data-to-simulation fitting method based on Markov Chain Monte Carlo is used to extract the photon yields and recombination fluctuations from the experimental data. The photon yields measured at the two lower fields are in agreement with those from literature; additional measurements at a higher field of 366 V /cm are presented. The electronic and nuclear recoil discrimination as well as its dependence on the drift field and photon detection efficiency are investigated at these low energies. The results provide new measurements in the energy region of interest for dark matter searches using liquid xenon.STAMPAenArticle10.1103/PhysRevD.97.0920072-s2.0-85048687794000433066800001https://journals.aps.org/prd/abstract/10.1103/PhysRevD.97.0920072018PhRvD..97i2007AFIS/01 - FISICA SPERIMENTALE
