07:00 : Started settings.
07:25 : Power equalized on 0837-198.
07:30 : \'/data1/gtac/cmd/42_055/42_055_17Sep2022_cmd.py\' command file started.
07:40 : Noticed that setup is with Beam-4 PA mode, observation requirement is one beam with Beam-2 voltage mode.
07:45 : So stopped command file and halted GWB.
07:50 : Restarted GWB with Beam-2 Voltage.

07:54 : \'/data1/gtac/cmd/42_055/42_055_17Sep2022_cmd.py\' command file started.
11:25 : Stopped command file and observing session over.
