<li style="margin-bottom: 0.1em;" class="">Considerable discussion was had on how to implement the FMWPC reconstruction, electron and mu/pi classifiers. A main issue is that Andrew has used the output of the kinematic fit for the electron/pion classifier he
has worked on up to now. This is readily available in the root files produced by the ReactionFilter plugin. Getting at the kinematic fit data further upstream in the factories is trickier. Simon noted that he had some code that did it which could possibly
be adapted for this need. He will look at it to refresh his memory.</li><li style="margin-bottom: 0.1em;" class="">In general, GlueX has 3 stages of reconstructed data: hddm -> rest -> root. Andrew asked if we could keep all of the AI/ML models at the end so they would only work with the final root files where the kinfit data is
available. David note that this would limit the ability to include this current monitoring system. Alex noted that there are some examples where the kinfit is used in a factory, <a rel="nofollow" class="external text" href="https://github.com/JeffersonLab/halld_recon/tree/master/src/plugins/Analysis/p2pi_hists" style="text-decoration: none; color: rgb(51, 102, 187); background: linear-gradient(transparent, transparent) right center no-repeat, url("data:image/svg+xml;base64,PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiIHN0YW5kYWxvbmU9Im5vIj8+CjxzdmcgeG1sbnM6cmRmPSJodHRwOi8vd3d3LnczLm9yZy8xOTk5LzAyLzIyLXJkZi1zeW50YXgtbnMjIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciIGhlaWdodD0iMTMiIHdpZHRoPSIxMyIgdmVyc2lvbj0iMS4xIiB4bWxuczpjYz0iaHR0cDovL2NyZWF0aXZlY29tbW9ucy5vcmcvbnMjIiB4bWxuczpkYz0iaHR0cDovL3B1cmwub3JnL2RjL2VsZW1lbnRzLzEuMS8iPgo8ZyB0cmFuc2Zvcm09InRyYW5zbGF0ZSgtMzYuNDY3ODA4LC0yNTguMzkwMDUpIj4KPHBhdGggc3R5bGU9Im9wYWNpdHk6MTtmaWxsOiMzMzY2YmI7IiBkPSJtNDEuNDcsMjU5LjQsNywwLDAsNy0yLTItMywyLDAtMSwzLTIuMjUsMSwxLDAtMy43NS0zLjc1LDAsMSwxLTIuMjUsMy0xLDAsMi0zeiIvPgo8cGF0aCBzdHlsZT0ib3BhY2l0eToxO2ZpbGw6IzMzNjZiYjsiIGQ9Im00My40NywyNjEuNC01LDAsMCw4LDgsMCwwLTUtMSwwLDAsNC02LDAsMC02LDQsMHoiLz4KPHBhdGggc3R5bGU9Im9wYWNpdHk6MTtmaWxsOiMxNWE1ZWE7IiBkPSJtNDAuNTUsMjYzLjljMC0wLjYyMTMsMC42MjEzLTAuNjIxMywwLjYyMTMtMC42MjEzLDEuODY0LDAuNjIxMywzLjEwNywxLjg2NCwzLjcyOCwzLjcyOCwwLDAsMCwwLjYyMTMtMC42MjEzLDAuNjIxMy0xLjI0My0xLjg2NC0xLjg2NC0yLjQ4NS0zLjcyOC0zLjcyOHoiLz4KPC9nPgo8L3N2Zz4K"); padding-right: 15px;">p2pi_hists</a> being
