Here is a summary of all the TDC Differential Linearity optimizations we made from December '03 up to now. As the values found today are very close to the ones measured in December '03 we won't commit any changes in the Reference files so that the results we will obtain will be comparable regarding TDC Differential Non Linearity. Shortly : on gzerol3, in ~orsay/manip/

In more details :
Routine : lm_main_loop() within the ROC terminal (No DAQ required - using GENEX internal signal) To retrieve slot#/logical address correspondance : look on g0ana, in ~/users/orsay/lindiff/lindiff_commands.helpTo find the minimum (optimized value for TDC Diff. Linearity tuning) :
On g0ana, ~/users/orsay/lindiff/lindiff filename

Note : negative value or values>255 mean that the minimum is out of the DAQ range (0-255). Negative values mean that the minimum has already be reached and on the other hand values > 255 mean that the minimum hasn't be reached...
