vaporpressure_bis

It seems that the vaporpressure_bis function is missing. Could you please help me locate that function? If I just change the vaporpressure_bis in the Data_extraction.m code to vaporpressure I get the following error at the end of simulation:

Done with ODE solver
now extracting data
Error using refpropm (line 464)
[TDFLSH error 5] One or more inputs are out of range; Temperature above 1.5x(upper limit): T = 370651 K, Tmax
= 1000.00 K; Pressure above upper limit: P = 2040.05 MPa, Pmax = 2000.00 MPa.

Error in vaporpressure (line 26)
pv = refpropm('P','T',Tv,'D',rhov,'PARAHYD')*1e3; % return value in Pa

Error in Data_extraction (line 22)
nominal.pv1(z,:)=vaporpressure(nominal.uv1(z,end), nominal.rhov1(z));

Error in runNominal (line 16)
Data_extraction;

Start with Data_extraction.m and runNominal, then inspect the vaporpressure and refpropm call sites shown in the error. Determine whether vaporpressure_bis exists elsewhere in the repository and establish how the simulation should complete without the reported out-of-range temperature and pressure failure.
