* prescales and masks are done manually without changing trigger databases. 
<p> 1. "Single tower Et > 2 GeV" and "Sum Et > 10 GeV" collect too 
much noise events, 
<br>     thus we will mask out "Single tower Et > 2 
GeV" which is much worse. 
<br> 2. Proton beam only can be used for CLC timing.  Use mod#2 
for this. 
<br> 3. With collisions, for the first hour, CLC is running standalone (to 
communicate with 
<br>     the  Beams' Div. about the collision 
position).  In parallel we will run with mod#1 without 
<br>     the CLC crate, which means we trigger 
on Sum Et and no bias.  Myron mode (early) should 
<br>     be used for this. 
<br> 4. After 3, the CLC will be integrated and the min. bias trigger 
will be tested. 
<br>      Use mod# for this run.

<pre>This sounds like a very bad idea, breaking the Trigger Database 
schema completely.   In this case you are not recording what 
you are doing in any sensible way.

Note that as of 10:00 p.m. Sunday, you can use the old 
scheme of specifiying the PhysicsTableName,PhysicsTableTag
and a L3TagSet=0 to use Level 1 and 2 -only tables.</pre>

Event id mismatch flooded errlog.

<!-- Comment: Sun Oct  8 19;14;13 comment by...AD -->
TSI00 has two suspended processes.  What's up with this?

<!-- Comment: Sun Oct  8 19;26;47 comment by...patrick -->
Possibly crashed trigger manager processes. Note the name of
the suspended task, then from the vxworks shell give the
command "tt name" using that name, and put the result in
the log.


<!-- Comment: Mon Oct  9 13;03;58 comment by...Steve Tether -->
The event ID messages were preceded by EventNotFound messages from every single on-line Scanner CPU. To accomplish that the SCRAMNet ring would have to have been broken for more than 2 msec! I can't think what would do that except some gross failure such a SCRAMNet module/bypass getting sick or someone power-cycling (or maybe SYSRESETting) an event builder crate. Did anyone notice if an SCPU rebooted itself at this time (it would have to have been one marked as off-line, otherwise data taking would have been stopped)?

According to fancy TSI scalar, looks like collision rate
is a whopping 1 Hz.  I don't know acceptance though...

At 20:39, MCR moved by ~20ns and rate increased to ~5Hz.
