Discrepancy in table TRACKSUMM of PTC tracking #962
Comments
I forgot to mention the version of madx

Thanks for the report. I will have a look. |
It is indeed very strange this behaviour and I have been looking to fully understand it this enitre morning. I have found that it is actually linked to particle 8 beeing lost which for some reason confuses it so if I make sure it doesn't get lost everything looks fine for me. I will continue a bit more and ask the other collegues in the team if they have any ideas... |
This bug was fixed in collaboration with @piotrskowronski . It was a problem with the indexing when a particle was lost. This meant that any particle that was lost after the inital lost particle gets the wrong coordinates. The PR that fixes this is #972 |
Thank you. When is it going to be included in the release? |
I track for 16 turns 15 particles with different X and PT, then in TRACKSUMM table I see that initial coordinates are correct but the final ones are mismatched, i.e. particle 9 having initial PT=-0.5, has PT=0.5 in the second half of the TRACKSUMM table, and particle 10 has correct values of PT.
Also X,PX of the particles 9 and 10 are different between TRACKSUMM and TRACKONE.
