Description
In GSLC products CRID 05023 (and maybe earlier?), the sigma0, beta0, and gamm0 LUTs cover additional area significantly beyond the extent of the radar swath, extending through the lower-right corner of the LUTs.
Two example granules which illustrate this.

Research direction
Start by locating the GSLC product handling for the sigma0, beta0, and gamm0 LUTs, then compare their coverage with the radar swath in the two example granules. Done means the LUTs no longer extend significantly into the lower-right area beyond the swath, with both examples checked.
