WARNING: Many pages in Howard's area can only be viewed by IE or Safari browsers.
I have attached pdf files  of these pages at the bottom.


The point to begin about the derivation of 'Probability of finding the correct hit' is here:
www-rnc.lbl.gov/~wieman/HitFinding2DXsq.htm
Once you are there you can follow (backwards) the whole history through the embedded links.

The 'Hit association formula' is then compared with MC (MathCAD) and agreement is achieved here:
www-rnc.lbl.gov/~wieman/HitFindingStrip2DMC2Gory.htm

The specific area where 'strips' or 'pads' are handled (some warnings are posted there too):
www-rnc.lbl.gov/~wieman/HitFindingPadVsStrip.htm

Part of the warnings is discussed in this page by Gene:
www.star.bnl.gov/~genevb/IST_Study/Corrections.html


A summary of HW work on this in a presentation form is here:

Gene's work was presented in March 2007 in a talk:
