Detailed Description

Class to estimate the Lambda using fitting equations in Xi&Liu10. See the documentation of the base class for more information.

With respect to the base class, the lambda is not estimated in a quantised form, bur rather using an interpolation considering the Mzams. The interpolating Mzams are the one reported in the Xu&Li errata (https://iopscience.iop.org/article/10.1088/0004-637X/722/2/1985): (1.,2.,3.,4.,5.,6.,7.,8.,9.,10.,12.,14.,16.,20.,50.,100.) Msun.

Each time a lambda estimate is needed for a star with Mzams=Mzams*, two interpolating masses are defined so that Mzams_track0<=Mzams*<=Mzams_track1, if Mzams*<1 Msun or Mzams*>100 Msun, the lambda is estimated using Mzams=1 Msun and Mzams1=100 Msun respectively The lambda of the interpolating tracks are estimated considering the current Radius, envelope mass and metallicity of the current track
