Hitfinding in E895 High Track Density Environment

Not TOO Old Topics

What about all those junk hits/pixels on the bottom of the TPC? (14aug97)
Padrow 51 for the low energy data.
- The problem (8aug97)
- The fix (13aug97)
A fix to the "Spatial Digitization" problem (29jul97)
Comparison of 1d and 2d hitfinders followed by JTF and BTF trackers.
- See this For all bombarding energies, the cpu times and performance of both hitfinders and both trackers in flow chart form.... very illuminating!
- Event-by-event study of both hitfinders followed by both trackers. Includes "residual hits" here
- Also, the numbers and distributions of TRK.FRAC_SEEN for 1d/2d + jtf/btf for 6 GeV data.

See pictures showing improvement (using 8 GeV data) of new hitfinder and double tracking:

What is it all about?

Some description of the E895 hitfinder

Switches for the hitfinder Analysis Module

Hitfinder status, getting the code, bug fixes...

Evaluation of the performance of the hitfinder with different settings

Time deconvolution in the OLD hitfinder with TRFF=1,2 and DECON=1,2

Determination of bad pads in pulser and real data.

Now get to work!!
