• > from cxi.plans import time_scans
    • Scan example with the combination motor lxt_ttc and three delay points -1, 0 and 1 ps: > RE(time_scans.time_scan(lxt_ttc, [-1e-12, 0, 1e-12], events=120*20, ntimes=2, randomize=True, record=True)), can also use scan the motor lxt or txt. 
      • lxt, txt and lxt_ttc are all in the unit of seconds
      • It takes list instead of nd.array for the delay points
      • Option to randomize 
      • It will randomize the time points each time it starts or repeats the scan
      • Give each delay point >=20s accumulation time
    • We should use the combination motor lxt_ttc for small scanning range to take advantage of the time tool correction for better time resolution
    • We should use the electronic motor lxt for big scanning range (hundreds ps to ns) to avoid messing up with the alignment of the txt motor
    • Pixel to fs calibration of the time tool can be done with either the lxt or txt motor, the window of the time tool detector is about 2-3 ps
