Now that the 3770 lattice design for the coming running period (3770_2p4_20061116)
has been finalized and successfully commissioned, the full compendium
of diagnostic analyses can be made available for comparison to the
2005 3770 lattice (12wig_20050626) and to the 2006 3686 lattice (3686_2p2ma_20060821).

For the purposes of this comparison, the tunes have been fixed
at (0.518/0.570/-0.089) for all analyses, as has the
prz1 amplitude at 3370 cu.

In 2005, we operated the 3770 lattice in an 8x5 bunch configuration,
so that is the choice for the two 3770 lattices. At 3686 we used
an 8x3 configuration, so the diagnostic analyses were done in 8x3.

The peak positron bunch current during the 2005 running at 3770 was about 2.0 mA/bunch.
At the 3686 the peak positron bunch current was 2.3 mA.

Injection Envelope and Electron/Positron Orbit Separation plots
---------------------------------------------------------------
Note added 8 Dec 06: The jobs 1489,1483 and 1490 have been
replaced with 1512, 1513, 1514, in which bugs in the tune
setting have been fixed.
Note also that the positron twiss parameters and orbits are
calculated with pretzel off and no BBI, while all electron
quantities include the effects of 1 mA/bunch of e+ in 8x5.
