In the 3MdB_17 database, all the models are run with Cloudy 17.01, and the reference of the models is PNe_2020. More effective temperatures are used:
All the models in 3MdB_17 have been obtained with Constant density (i.e. no Gaussian density law as in PNe_2014). A total of 724,386 models are in 3MdB_17, from which 116,121 have com6 =1 (see below).
The python script used to generate the models is there: https://github.com/Morisset/pyCloudy/blob/master/pyCloudy/3MdB_17/make_PNe_20.py
