1. dN/dx method has been described during the presentation on PWGC meeting, September 30, 2016, https://drupal.star.bnl.gov/STAR/system/files/dNdx_rev3.pptx.pdf
 2. List of the code modification due to dN/dx method has been published at https://drupal.star.bnl.gov/STAR/blog/fisyak/list-modications-due-dndx-method-0
 3. Run XVI AuAu200 and dAu200 dE/dx calibration has been redone with "less aggressive" ADC correction (see http://www.star.bnl.gov/HyperNews-star/protected/get/startpc/1665.html). The new calibration has been put in MySQL (Saturday October 15, 19116 @ 19:11) and still waiting for completion of the verification jobs  in dev which were submitted (10/15/2016).
The old calibration has for dE/dx fitted some systemtics with respect to prediction for very high ADC values (protons)

New calibration mitigates this effect

The fitted dE/dx values are used for nSigma calculation it is better to have properly centered.
