class PDynamicData: public TObject

returns the partial decay width of the decay channel "didx"
for a given "mass"
If no primary channel model has been found
return the static width

 Total decay width by pid & invariant mass (GeV/c^2).

 For most purposes GetParticleTotalWidth may be used for the total width.
 GetParticleTotalWidthSum should be used instead only for sampling BR's.
 Due to roundoff error in the interpolation, Width() returns a value
 that differs slightly from the sum of the partial widths Width1().
 As a result, small branching ratios (e.g. electromagnetic processes)
 may never be sampled if Width() is used. For this reason, if a BR is
 requested, it is best to calculate the total width explicitly by
 summing the partial widths for any given mass.

 flag=1: take into account only hadronic decays

 returns branching ratio by mode index and mass (GeV/c^2)

 list branching ratios of particle id for mass m

 returns the index of a decay mode for particle pid=id of mass m (GeV/c**2)
 selected randomly, consistent with the branching ratios

 returns the number and pids of the decay products for the decay
 of particle pid=id of mass m (GeV/c**2), via a mode selected
 randomly, consistent with the branching ratios
 In addition, it does not hurt to return the index (IF)

to stop endless loops

returns the primary decay model

returns the primary decay model

returns the secondary decay model

returns the primary particle model

returns the particle width if a models exists, if not the static
width

return the mass-dependent width if a model exists
no mode: use the fixed Breit-Wigner with the total width

 Returns the total number of embedded recursive decays
 (TDepth if flag=0) or the number of embedded recursive
 hadronic decays (HDepth if flag=1).
 The default value 0 means the index has not been accessed yet.
 Zero depth corresponds to index -1.
