beam through tower3 side, no ACD tile; BT50, BT51 have a CNO trigger engine which is not satisifed - most events are therefore read with the std engine auto-range, ZS associated with any other trigger than CNO |

noticed larger fraction of TEM errors (from 2% to 3.5%) - probably due to higher rate in first part of spill when getting beam back from therapy |
