Notes. Obs. #: Number of observation by date, 1: 2023-11-05 (00:28), 2: 2023-11-05 (23:43), 3: 2023-11-07, 4: 2023-11-08, 5: 2023-11-10, 6: 2023-11-13, 7: 2023-11-14, 8: 2023-11-17, 9: 2023-11-22, 10: 2023-11-23. Hβ: The Hβ line profile is best fit by the sum of a wide absorption line and a narrow emission line. The value given is the equivalent width of the emission line. vβ: Radial velocity of Hβ emission line relative to the LMC. HeI 4921: Equivalent width of HeI 4921 absorption line. vHe: Radial velocity of HeI 4921 absorption line relative to the LMC.
