   Ciao a tutti,

   I would like to add the following items to my weekend shift-report.
Note that these observations are based on runs 18294-18303.

(1) Trigger rates
    TOHM: 4T10 is hot (~10mHz)
          3W10,3T06,5W08,5W09,5T17,6E10 result dead. Note that 3T06,
            5W08/09 and 5T17 have been disconnected. I don't recall
            anything regarding 3W10 and 6E10.
          1W03,2W08,3E10,3E11,6W09,6E09,6E11,6E13,6E14 have very
            low rate (~ 1hit in 2 days)
(2) Stopmaster
    In some runs (for example, 18294) there are many (30-40) fake hits
    on cross-uVAX (SM2/3 and SM4/5) events
    During run 18303, there was 1 event that SM4 STPM gave no-Qs.

(3) LaMOSSKa
    During run 18301, there were 10 (mostly unjustified) triggers on uVAX#3.
    In fact, uVAX#3 LaMOSSKa is firing 3-4 times a run with no other trigs.

(4) WFDs
    During run 18303, evt. 280, SM3, CH30 & CH31 gave the "usual" bogus
    disc. bit and timeword problem. During the same run, there was 1
    5C74 and 1 5C54 (VME/READ and VME/WRITE) errors. Could it be the
    event that also had the no-Qs from the SM4 STPM ??

That's it for now,

Ioannis
