Research direction

Start in python/packages/nisar/products/writers/SLC.py around line 489 and inspect how the referenceTerrainHeight dataset is populated for RSLC products. Trace the source of the expected terrain-height values and verify the resulting H5 vector is not filled with zeros; add or update a focused test if the surrounding code provides one.
