Hello all, 

Our paper is ready for the PWG review, please find all the information below:

Title: Measurement of directed flow at forward and backward pseudorapidity in Au+Au collisions at 27 GeV with the Event Plane Detector (EPD) at STAR

Target Journal: PRC

Replies to PWGC comments:
To answer the only question raised in the PWGC preview:
Slide 7
Q. How good is TPC Psi1 resolution?
A. Something like ~0.1 but need to check

The resolution plots can be found on page 20 of the analysis note. In summary, after all the weighting and shifting, the TPC event plane resolution ends up between 0.02 and 0.08, peaking around the centrality of 20 ∼ 30%.
