Dear Colleagues,<br>
<br>
Based on substantive responses from several of you, we have posted a
revised Monte Carlo dst format spreadsheet on docdb. It does not
change the average size of the event record very much, but there are
significant fixes/improvements based on your feedback.<br>
<br>
The purpose of this exercise is so that I can generate a significant
fraction of a year's worth of bggen MC data for analysis by grad
students who are hoping to finish their thesis within a finite time,
and would like to present in it an end-to-end analysis of simulated
GlueX events, and show that their favorite final state can be
reconstructed and separated from the background sufficiently well to
allow a PWA. I say this because I fear I may have raised more
attention from the core software people than it is worth.<br>
<br>
This little project should not be allowed to distract the software
working group from its focus on core software development. This is
not supposed to be a major software development project. All I
intend to do is to capture a minimalist impression of the
reconstruction objects from the truckload of stuff spit out by
danahddm, and "freeze-dry" it into a file stream. At some later
date my little plugin will "thaw" out these records, and
reconstitute facsimilies of the original objects. <i> I do not want
to create any new classes, such as <b>DChargedTrackCandidate_compact
</b>or anything of the sort<b>.</b></i><b> </b>The software
working group may want such classes, and start planning accordingly,
even using our template as a starting point for such a design. That
would be fine. For me, the gazillions of the various reconstruction
objects that already exist, with all of their redundancies and
overlaps, is a bit bewildering! I certainly do not want to add
another layer of objects of my own to the mix.<br>
<br>
I just want to "fax" a minimal set of currently existing
reconstruction objects to myself in the future. A fax is not a
perfect copy of the original, but if you can read the words on the
page, it is good enough. That is the goal I am working toward. I
will follow this message with a list of the detailed changes we made
based on feedback from Paul and David, and responses to some of the
comments.<br>
