The following are the changes made to the original paper:

1. Section 2 (Experimental setup) Last paragraph third sentence -

For each combination of thermal load and equivalence ratio, the fraction of hydrogen in the fuel was varied in increments of 10%, until flashback occurred or the thermoacoustic pulsations were strong enough to damage the combustor windows. In total, 48 flame conditions were successfully measured.

2. Section 2 (Experimental Setup) Table 1 column 3 -

Table 1

Different dynamical states observed by increasing HFF (%) for $P=$ 10 kW, 15 kW, and 20 kW for $ϕ$ = 0.65 and 0.8. The expanded forms of the abbreviations used in the table are provided in the nomenclature section. NA refers to the nonavailability of data at that conditions due to the breakage of the quartz window allowing optical access to the combustor.

3. Section 3 (Results and Discussion) Second paragraph sixth sentence -

At the higher thermal power (P =20 kW) and $ϕ=$ 0.65, the system exhibits low amplitude P2 LCO for lower HFF, while intermittency and P1 LCO are noticed at higher HFF.
