Prerequisites
NOTE: Be aware that all issues are publicly accessible and viewable. Thus please do not post any code or other content that is protected intellectual property or under copyright.
Before posting an issue, please:
* Check the FAQ for common solutions.
* Check that your issue isn't already filed under REFPROP Issues.
* Check the documentation.
You can also use markdown to format your issue: GitHub guide on Markdown. If you have code snippets, please use a code block to ensure that the formatting remains legible in the web interface. For instance, surround your code in triple backticks:
print('Hello world!')
Description
My problem in a nutshell,
a) REFPROP enthalpy and entropy datum values for Para-H2 are zero at NBP.
b) I would like to be able to change the enthalpy datum value of Ortho-H2 from 444.92 J/g to 703 J/g (rounded value).
With this change the enthalpies of O-H2 and P-H2 would differ by the exothermic heat of conversion.
Is this possible? If so please let me know how. (I am not a VB programmer).
If the enthalpy datum for O-H2 is adjusted as suggested, it may be advisable for its entropy datum to be changed.
Your advice on this point is also appreciated.

Expected behavior: [What you expect to happen]
Actual behavior: [What actually happens]
Versions
REFPROP Version: [REFPROP version you are using] version10 Operating System and Version: [OS you are running REFPROP on] Windows 11 Access Method: [How you are accessing REFPROP (i.e. Python, other wrapper)]: Standalone REFPROP via links to Excel and via UniSim using REFPROP Thermo.
Additional Information
I obtain the same result, so this is a fundamental issue with the enthalpy datum for ortho H2.
The enthalpy datum value for para-H2 is liquid at NBP. The value for ortho-H should be greater than this by the heat of conversion at about 20.3K.
If possible, please post examples and/or screenshots of the issue.
