Dear all,

I noticed in the Pirana 23.1.2 release updates, there is an update to the formula used for the calculation of RSE for sqrt(exp(OM^2) - 1) transformed Omega and Sigma.

Previous formula: RSE% = %RSE_{untransformed}/2

New formula: RSE% = exp(ParameterValue)/ (2*(exp(ParameterValue) – 1)) *ParameterValue*(%RSE_{untransformed}).

However, I am unable to find additional background information on the switch. Would appreciate it if someone could shed some light on this.

Many thanks.
