Definition of psi0 in vardtc

[Hebbalali]

Hello,
Firstly i would like to thank you for sharing this implementation online.
I have one question about the definition of the stastistics in vardtc for uncertain inputs.
In the code it's written:

        if uncertain_inputs:
            psi0 = kern.psi0(Z, X)
            psi1 = kern.psi1(Z, X)*beta
            psi2 = kern.psi2(Z, X)*beta

Then in the computation of the likelihood:

logL = -(output_dim*(num_data*log_2_pi+logL_R+psi0-np.trace(LmInvPsi2LmInvT))+YRY- bbt)/2.-output_dim*logdet_L/2.
My question is: shouldn't it be psi0= kern.psi0(Z, X)*beta or in the logL be psi0*beta ?? because in the logL psi0 should be scaled with beta
