Hi, it was me who committed the calibration to the database in 05. I did a comparison with version v1 (before the calibration in 05) and v2(after cal in 05), for specifically this run 7634, there was not much change (at least could not be seen by eye) in the tof1 and tof2 behavior because of the calibration. Both dst files can be found at /brahms/data21/data/run03/dau/200/r7634/dst/. See the attached gif files. (red dots are for v1, and green dots stand for v2) It will be very nice if someone can help me to improve this calibration. I have mentioned in the mail to Flemming and Ramiro, those scripts I had used for those calibration was modified a bit to adapt to the latest gtr files, based on the calibration scripts in brat.
