Hello LCD developers:

I have been developing a JAS particle ID package for LCD studies based 
on a pre-prototype provided by Gary Bower last fall.
I will first apologise to Gary for whatever monstuous things I have done 
to his progeny! However, I do recall him telling me I had free reign...

As the saying goes, there are "many ways to skin a cat" and as my 
knowledge of Java increases I can see numerous ways that one could 
implement different, but hopefully equally valid/useful, solutions. Now 
I had gone through a few iterations I would like to have the LCD 
simulation and reconstruction architects take a look before  I spend a 
lot more time on it.

The package is structurally functional but the physics of the PID 
simulations has not been fine-tuned. I have tested it with event 
generator StdHep (a Pandora/Pythia example is provided) input, doing 
MCFast on the fly; and with LCD simulation (.lcd files only). The PID 
code it the same in both cases, it uses the standard TrackList and the 
new ReconstructedParticleVector. There is also a new event display (an 
modified version of the old one, a WIRED version may come later) that 
allows particle IDs to be display (and a table with ID goodness etc.). I 
will clean up the code, complete documentation etc. after I get some 
feedback.

I have posted installation instructions and some documentation on this 
web page:

http://grid.ifae.es/datagrid/wilson/flc/BobWFastPID/
(for the curious you can also peek at some of the DataGrid stuff I have 
been doing this year  -- there may be a JAS connection some time down 
the line).

As the the page warns: BEWARE. It is possible that this package will 
interfere with your usual flawless JAS operation.  So try it only if you 
have your own version of JAS installed, so that you can drop the new 
.jar files into the extensions directory... and equally easily remove 
them again if they break things.

I would like this package to be available for inclusion in the Snowmass 
CD-ROM, so feedback would be appreciated as soon as possible. Please let 
me know if you itend to try it, just so that I know whether to expect a 
response.

Best regards,
Bob
