- The short spike at T+54.4 s is due to detector glitch. 
- The 1-s peak interval found by the autu pipeline is the glitch. Therefore, the real 1-s peak interval is found by manually removing the glitch in the light curve (i.e., reset the value to zero). The 1-s peak spectrum and the spectral analysis are also created manually.
- The large pulse in the BAT raw light curve from ~T+400 s to ~T+550 s was from a background bright source (MAXI J1820+070) that enters the BAT FOV during this time interval.
