Hold on, I yet haven't had a chance to do it but I'll post the modified script later today.
Wouldn't do it any other way haha!
Ensuring alignment and a tight bond on so many pieces was a bit nerve wrecking. For anyone else going this route I highly recommend using super tacky construction glue. The initial hook you get from the tacky glue is very useful when it comes to aligning the petals in the throat. But make sure to use clear tape on any aligment jigs you might use to avoid them sticking to the waveguide.

So I gather you didn't use the provided assembly jig, right? Is that not the way making it easier?
I certainly did. And it was very handy. But my print tolerances were all over the place, so i had to use all the tricks to ensure a good fit. (I don't have permanent access to a printer, so I've used three different printers with more than 4 different PLA filaments)

Here you go. You just need to set GnuplotCode in your Report definition, and of course disable any normalization as well.
It's possible to set the SPL range to fixed or automatic (see SPL_0, SPL_1 and the instructions in the file).
ABEC outputs the file "Spectrum_ABEC.txt", which is then converted by Ath to a set of simple text files read by gnuplot.
It's described in 6.14: http://www.at-horns.eu/release/Ath-4.8.2-UserGuide.pdf#page=60

I cant install gniuplot on the VM a run ATH on... but ATH is involved with -r extension - this means I can not move the files to OSX and run gnuplot from there...

You can take the files intended for gnuplot (simply all the *.txt files in the 'Results' subdirectory, after "ath ... -r" is executed) and run gnuplot anywhere else, but it won't be very convenient.

I dont know enough of win to get why I cant install it in my ARM64 based VM... hence: https://www.diyaudio.com/community/threads/gnuplot-in-vm-on-mac-x86-64.413839/#post-7708319

Thanks, Marcel. Unfortunately, I'm not quite there yet. I put the new GNU script in the right folder and I added it to the GnuplotCode in the Report definition.
ATH is now using this script. In the first run, I didn't see any SPL data. The default SPL range is 20 to 70. I then set the SPL range to automatic, and now I get the results below. However, the SPL results are still normalized. You said "[...] and of course disable any normalization as well". Where do I do that? I went through the GNU code and the only place where normalization is mentioned is in regards to the polar map. Should this be configured elsewhere?
In the ABEC Observation Script if you already have the project or in the Ath Script if not or re run it. Remove NormAngle = from the Ath script or comment out NormalizingAngle= in the ABEC script, rerun the observsations and save the ABEC spectrum again to avoid the data already normalized on entry.
As fluid says. BTW, the polar map will always be normalized I think (at 10deg, which is the default value, IIRC). To change this would require some modifications of the Ath code.
- You can also change the way the elements are driven - the default is constant acceleration. Sometimes it's handy to use constant velocity. This is set in the ABEC observation script. For normalized results, this makes no difference of course.
In the Ath script, this can also be set:

In the Ath script, this can also be set:
Code:
ABEC.DrivingType = 1 ; constant driving: 1=acceleration, 2=velocity
ABEC.DrivingValue = 100 ; use much lower value for velocity

Thanks, guys!
I simply put a [ ; ] in front of [NormAngle = 10], that did the trick.
Now marvel at this beauty!
