**HCal
***issue between TI, one bad transceiver in one HCAL TI, replaced and working in stand alone
+
***ROC16  - ROC17 - seems better with fixing the busy
***fixed prescales ( bug in readout list ) - now working
+
***taking cosmics and looking at LED - 1 LED run and 1 cosmics - most PMT calibrated - some have very long tail ( not light leak - seems linked to PMT - need to investigate and replace or move to edge of acceptance
***cosmics calibration on-going
+
***combined run - replayed run - timing need to be adjusted for TI - can look at it today now TS is working
+
***load slot error
+
***Bryan managed to convert script in systemd, now threshold are restored when crate is power cycled ( running )
+
***EDTM pulser work : mostly installed but need to be tested.
