Pcal lines running at 534.7 Hz (Xarm) and 540.7 Hz (Yarm) have been switched with one-another to cross check the calibration between the two arms. Now, the Xarm has a line at 540.7 Hz and Yarm as a line at 534.7 Hz. These will be switched back to its original position once we have a IFO locked data.This study is the continuation of what we reporrted in LHO alog 17582.
The Pcal lines are switched back to its original position.
