Hello All, Recent modifications to tracking code in lcsim resulted in a degradation of track parameter resolutions for collider simulations. Jeremy and I wrapped these modifications to lcsim which were introduced by HPS and we updated the hps-java to implement the HPS-specific changes. I believe these now revert the tracking to what we had previously. Please check out the head versions of lcsim and hps-java and let me know if you can confirm this. I have run the tests, but I am not confident that the tests are rigorous enough to catch such effects (although they should). Please let me know if you have any questions or need any additional information. Thanks, Norman ######################################################################## Use REPLY-ALL to reply to list To unsubscribe from the HPS-SOFTWARE list, click the following link: https://listserv.slac.stanford.edu/cgi-bin/wa?SUBED1=HPS-SOFTWARE&A=1
