[Halld-physics] Physics Meeting on Monday

[Curtis A. Meyer]

Even if they are just there as "sample" or "example" code, they could be useful. Probably
anyone doing a full analysis will want to at least verify that it makes sense, and more likely
do some tweaking.

>>> Now that the analysis tools are at a point where everyone can start (relatively) easily using them, perhaps we should use them to systematically study the various channels we want to search for hybrid mesons (and other physics).  If we all start taking a look at them (with the ANALYSIS library, the BDT, and AmpTools), we can learn about the performance/ability of the GlueX detector to isolate these channels, and what the remaining backgrounds might be.

This would be a huge step towards getting us ready to analyze the experimental data when it comes in.
