Work during tomorrow's access:

1. Remove 8 ns from gr4 in shower branch of SUM8 to linear sum P/S 740.

2. Add 16 ns in gr1 in shower branch of SUM8 to linear sum P/S 740.

3. Add  8 ns in gr2 in shower branch of SUM8 to linear sum P/S 740.

4. Add  8 ns in gr3 in shower branch of SUM8 to linear sum P/S 740.

5. Only in gr5, add 12 ns cables in both narrow signals that go to the ANDing module 
   so as to see if it makes a difference compared to other groups. This is anticipated
   since all these narrow signals are faster by about 10-14 ns compared to their wide
   counterparts.

6. Check if there is any smaller rate clock (less than 1024 Hz).

7. Change T3 to T6 to electron triggers from gr3 to gr6 [use only EL-narrow? If we
   want wide also, then can not cover gr3-gr6, only 4 triggers can go to Trigger Supervisor].
   (keep current T6 as it is) and re-align these triggers to T1, check T7 too for re-alignment.
   Also find out whether the T6 is from electron narrow or electron wide. 
  
   For T3 and T4, take outputs from the P/S 758 in veto part
   For T5, take notNIM from ANDing module and invert it using P/S 758 (same way as current T6).

  

8. Add tagger in group5-8: 

#  Add another P/S 740 module to linearly sum preshower to DM signal with the tagger.

#  Also needs to add tagger in existing linear sum (P/S 740 for TS) and in veto-inputs. 

#  In veto inputs, add tagger in the 755 first two quads.
 
#  Adding a 740 module introduces extra 12 ns delay. 
   Also add 12 ns in TS to Discriminator for these groups only.
