The frame is labelled as a full frame product, but overviews and data in the file suggest partial coverage only.
The corresponding GCOV
NISAR_L2_PR_GCOV_026_026_D_065_4005_DHDH_A_20260722T001541_20260722T001616_P05023_N_F_J_001 also appears to be labelled as full frame even though coverage appears to be partial.
