This blog keeps track of incremental improvement of BTOW +ETOW peds & status tables. All available data for days 76-103 are processed (sampled).

1. Iteration #4, April 22.  Justin produced peds & status tables based on minB events. Matt uploaded them.  Jan accumulated pedestal residua for the first 3K L2W events in every fill, discard towers w/ status!=1 for both ped & status. Attachments A), B) show file-by-fill 2D spectra for BTOW & ETOW , respectively.
   • Conclusion 1:  all pedestals are reasonable, very good.          

      

   • Conclusion 2: the following blocks of BTOW towers should be masked as bad in DB

     Table 1, Problems w/ BTOW status tables

     page	fill	remarks
     p9	F10415	kill 1 tower, ID~595
     p12-14	F10439, 448, 449	kill 80 towers, ID~600
     p21,22	F10471, 476	as above
     p23	F10478	kill 80 towers, ID~1550
     p29-37	F10507- 532	kill 8 bands x ~8? towers, ID~500-600
     p38,39	F1035,536	as above +kill 4 bands x ~8? towers, ID~750

      

   • Conclusion 3: the following blocks of ETOW towers should be masked as bad in DB

     Table 2, Problems w/ ETOW status tables

     page	fill	remarks
     p5	F10403	all ADCs are stuck at one value, full ETOW needs masking
     p8	F10412	mixture of as above and good data - mask bad time intervals
     p14-16	F10449-454	kill 4 blocks of ~6 towers for X=200,260,320,380
     p17,24,34,36,38	F10445,482,527,531,535	mixture of problem on page 5 and good data - mask bad time intervals
     p28	F10505	all ADCs are stuck at one value, full ETOW needs masking
     p5	F10403	can you mask this one tower
