[Halld-tracking-hw] Track length from CDC signal

[Naomi Jarvis]

This section

https://halldweb1.jlab.org/wiki/index.php/CDC_signal_integration_new#change_in_gradient

is showing the relation between CDC "signal duration" (similar to time
over threshold) and the track length that was calculated by the
trackfitting in my analysis code.  In the plots pklength is the signal
duration and tracklength is the trackfitted path length through the straw.
  For the larger signals (detector tilted) there is a fairly clear
relation between the two.

Would it be useful to output the signal duration from the CDC as well as
the two planned quantities (time and something representing dE)?

Naomi.

>>         We will have our next tracking meeting on Wed. July 18 at
>> 11:0am.
>> The agenda has been posted on the Wiki, and the item of note is
>> calibrations.

>>          Starting this meeting, we will no longer have the tracking

>> component of the meeting as it appears that this is being covered
>> well in both the regular offline meeting and the physics meeting.
>> (If there are loud and persistent complaints about this decision,
>> we can reconsider it;-) )
