data times must be displayed incorrectly
Attached is a trend I made of several things from May 27th 2022. The last column here is the problem, I'm not sure if this is an ndscope problem or if the data time stamping is wrong.
The guardian state 520 is MAXIMUM_POWER, when the input power to the interferometer (IM4_TRANS_SUM) is 40W (back in May). Looking at the trends in the 3rd column, these aren't possible. The power on IM4 trans and the arm circulating power drop as though we lost lock, but the guardian state doesn't recognize that. Then the power on IM4 trans and the arm circulating power come back as though the interferometer relocked, which isn't possible without the guardian state changing.
I added these three traces (IM4_TRANS, IM4_TRANS_SEG1, and X_ARM_PWR_CIRC) using the interface where I add plot to row, add channel, while the rest of the traces here were added from the command line.
