Research direction
Start by inspecting RUNW generation for /science/LSAR/RUNW/swaths/frequencyA/interferogram/HH/ionospherePhaseScreen and ionospherePhaseScreenUncertainty, then compare the corresponding GUNW datasets and the XML specifications. Done means both RUNW datasets contain min_value, mean_value, sample_stddev, and max_value attributes.

Description
Overview
In RUNW sample products generated with CRID 05016, ionospherePhaseScreen and ionospherePhaseScreenUncertainty no longer include statistics attributes. The 'min_value', 'mean_value', 'sample_stddev', 'max_value' attributes are missing.
Affected Products:
- RUNW: ✗ Affected - 2 datasets have missing statistics (see details below)
- GUNW: ✓ No issues found

Missing Attributes:
- These attributes exist in the corresponding datasets in GUNW
- Per the XML specs, these attributes should also exist in RUNW
Dataset: /science/LSAR/RUNW/swaths/frequencyA/interferogram/HH/ionospherePhaseScreen
Missing Attributes: {'min_value', 'mean_value', 'sample_stddev', 'max_value'}
Dataset: /science/LSAR/RUNW/swaths/frequencyA/interferogram/HH/ionospherePhaseScreenUncertainty
Missing Attributes: {'min_value', 'mean_value', 'sample_stddev', 'max_value'}
