Hello Brennan and all

 I noticed that there might be some confusion among us. Sometimes, the 
acceptance of TOF is written as |eta| < 1, while at other times, it's 
|eta| < 0.9.
In the proposal for the TOF detector, I found that the specified 
acceptance for TOF is |eta| < 0.9.
(https://drupal.star.bnl.gov/STAR/system/files/tof-5-24-2004.pdf)
During the analysis process, the Vertex Vz and the acceptance are 
correlated. Some analyses have a relatively wide Vz range, combined with 
specific decay kinematics, which allows the use of the TOF detector even 
when the charged particle tracks are at eta > 0.9 or eta < -1.
However, from the perspective of the STAR experimental setup, the TOF 
acceptance is indeed |eta| < 0.9.
