Version 2.3.12 January 27, 2023

• Fano factor for all ER (betas and gammas) now a free parameter (combined-E scale) with a default of 1 and no energy or field dependence by default any more
• Allowing reverse compatibility with the older more complicated Fano factor model (energy and field dependent) for LZ SR1 especially, by entering a negative value.
• Recombination fluctuations low-field, baseline amplitude lowered from 0.05 to 0.046 everywhere, to better match the ER band widths in LZ SR1 & XENONnT SR0.
• All free-param m’s (in the sigmoids) in the GregR beta ER model are now settable by the end user. Use -1’s to get the defaults
• A bug fix within the Liquid Argon modeling: alpha-particle light yields increased after double-counting of quenching was addressed (Kate K., MEPhI)
