(apologies to those I couldn't see)

Hardware Status
---------------
o New fibers are here
  - they are of the right length

o TAB/GAB crate power supply attached to load
  - burning smell noticed
  - call into Wiener

o Bug in Monitoring program fixed
  - program has now run for 20 hours without problems

o ADFs
  - install ATCs LVDS cables first

o Cabling/Installation
  - have come up with a plan for safely disconnecting BLS cables
    . and protecting them
  - note: decalbing will also involved removing existing ribbon cables
    . this will add more time to decabling (should be w/in
      contingency)
  - will also need to install a protective cover on Master Clock rack
  - need to get remaining LVDS cables from Nevis as quickly as
    possible 
  - should have ORC people look at crates before cabling


EM Algorithm Discussion (cont): S.Lammers
-------------------------------
(see plots linked off the agenda)

o Position Resolution: effect of removing masks
  - difference in resolution b/w w/ and w/out masks is negligible

o Based on this it seems safe to get rid of the masks, however...
  - it is possible to retain the masks in the firmware (enableable
    with a downloadable switch) but only if we switch to indexing the
    EM objects by the upper/right corner (rather than lower/left as it
    is now).
  - Consequences
    . EM and Jets will be indexed using a different convention
    . have to change the L1Cal EM simulation
    . have to change CalTrack simulation and firmware
      > preliminary discussions w/ Stefan Anderson indicate that this
        is probably not a big difficulty for them
  - The safety we gain by doing this is probably worth these
    consequences though
    . if you can think of a reason not to do this, let us know as
      quickly as possible
