Found an offset before and after bends in emma.xml when running the following command on hlx:

/home/cbarquest/acc/lib/xml2optr.py '/home/cbarquest/acc/isac/path/emma.xml' -E 79.3591 -q 7 -m 33533.80 -Q 0 -t '/home/cbarquest/acc/isac/tune/emma.xml' -o '/home/cbarquest/acc/lib/emmatest/'

The output I put for the first version in beam/envelope highlights the drift that I had to manually change for the generated xml2optr sy.f file to match the reference sy.f output:

Drifts before and after the bends were off by +/-26.18cm. Note the sequence emma.xml file was originally generated by optr2xml(I think?) so not sure if the position calculation is off in optr2xml or xml2optr.

Here are the relevant emma.xml path/sequence/tune files:

• Path emma.xml
• Sequence emma.xml
• Tune emma.xml

And here are the reference sy.f and data.dat files:

• Reference emma sy.f
• Reference emma data.dat
