Top panel: Distribution of the time-averaged PF as a function of spectral peak energy for GRB 220107A (pink triangle) compared with samples from GAP (red marker), POLAR (green marker), and the AstroSat (orange marker) five-year GRB polarimetry catalog (Yonetoku et al. 2011a; Kole et al. 2020; Chattopadhyay et al. 2022). No clear trend emerged, consistent with variable prompt-phase polarization in GRBs. Bottom panel: Time-averaged PF plotted against the low-energy photon index for GRB 220107A (pink triangle) in comparison with GAP, POLAR, and AstroSat measurements. Overlaid dashed lines represent theoretical synchrotron cooling models: pink (synchrotron slow cooling; α = −2/3) and blue (synchrotron fast cooling; α = − 3/2).
