L3 run periods in RunIIb

Release	Triggerlist	Runs	Comments
p19.L3.02	v15.00 -> v15.16	221993 -> 225821 June 13th 2006 -> Sept 29, 2006	First RunIIb release, warts and all ! (No Layer 0)
p19.L3.03	v15.17 -> v15.54	225844 -> 231955 Sept 29, 2006 -> April 4, 2007	No Layer 0, some tracking improvements.
p19.L3.05 p19.L3.05a	v15.60 -> v15.66 v15.67 ->	231920 -> 231984 231985 ->	Ongoing. Layer 0 implemented, plus major bug fix in tracking (skipping a layer in the CFT now works). Runs taking with v15.60 (231920 -> 231985) have a wrong DCA parametrization (affects b-tag triggers). The online versions of p19.L3.05 and 05a are identical except for a bug fix in the tracking filter to fix a double deletion of a tool. For offline studies always use p19.L3.05a.

How to run RunIIb TrigSim (for Level 3)
The basics:
Setup a release area (you know the drill) using p19.L3.02/03/05a as basis.
setup d0tools
Make sure you have an input file and a trigger list. The triggerlist must be called 'level3.sim' and it must be put in a directory called 'trigsim' in your working area.
runD0TrigSim -l3only -maxopt -format=[data or mc] -filelist=[whatever_you_called_it] -name=[some_sensible_name_for_an_outputdirectory]

Data and MC samples:
Please read through the comments on the sample, you'll save yourself a lot of grief.

p20 Monte Carlo for Level 3 studies available (includes L0)! Please also read this.

p17 Monte Carlo for Level 3 studies available !
Here is an excerpt of the infamous "list all MC request ever made" MC production webpage.
This one starts at request 30000, so you might actually be able to load it.

Reco'ed data with the raw data chunk preserved (i.e. TrigSim compatible): Data samples.
