Computers and software • Quintessence module

Dear all,

I have a question about the default oscillating quintessence module introduced in DarkEnergyQuintessence.90. If I want to use this module in CosmoMC, is it necessary to define a constraint relationship among the density elements at present, considering the parameters of the model used in CosmoMC?

For example, would it look something like this: parameter_1 = 1 - {Func(parameter_2)+ Sum(Omega_i)}?

I understand that the relationship is included in the file cosmologyParametrization.f90, specifically with the equation: CMB%omv = 1 - CMB%omk - CMB%omb - CMB%omdm. However, for quintessence, is it necessary to establish a new constraint relation in CAMB to define a new parameter space? Or should I use these parameters independently to make extended parameter space?

I have modified the file for my model but to use it for CosmoMC I am unsure how to do that.

I hope I have explained my issue clearly.
Thank you
