Is there a way i can know the rotation angle between the equatorial and azimuth mount?

Hi, i have been browsing through the Q&As to look for a way to rotate the view or the orientation so as to adjust to camera view, pretty much the same with issue 3705: #3705, as far as i ve found out it still has to be done manually i suppose?
Meanwhile switching between equatorial and azimuth mount is possible:
with equatorial mount:

with azimuth mount:

I would like to know the rotational angle between these two frames(or how much the the red camera rectangle rotated). Of course i can calculate this value with some post processing but would be helpful if i cant access it directly. Also is this angle fixed? Thanks

The parallactic angle is available at least in the infomap accessible from Scripting.

Thanks! Is the function getParallacticAngle available in the script console? How can i call it? I tried core.getParallacticAngle but it's not recognized
