SAR K-ARD NRB Quality Assessment — M0: Metadata and Product Completeness Validation
==============================================================================
Product/Tile : Tile 12SUC33, acquired 2023-10-08 (12SUC33_20231008013527_K5_ES02_NRB)
Grade        : Pass

Product type                                        : NRB
Threshold-requirement errors                        : 0
Product files present                               : 8 of 8
Missing files                                       : None

Grading rule: Pass if no threshold-requirement violation is found and every expected product file is present; otherwise Fail.

SAR K-ARD NRB Quality Assessment — M1: Histogram Uniformity Analysis
==============================================================================
Product/Tile : Tile 12SUC33, acquired 2023-10-08 (12SUC33_20231008013527_K5_ES02_NRB)
Grade        : B

Standard deviation, gamma-naught E (sigma_E)        : 7.726 dB
Standard deviation, gamma-naught T (sigma_T)        : 7.726 dB
Mean terrain slope                                  : 2.012°
Relative difference (sigma_E − sigma_T) / sigma_T   : -0.0001
Basis of grade                                      : The mean terrain slope is 7 degrees or less, and sigma_T exceeds sigma_E by less than 10 percent.

Grading rule: Mean slope > 7°: A if sigma_T is lower than sigma_E by 10% or more; B if lower by less than 10%; C if sigma_T is not lower than sigma_E. Mean slope ≤ 7°: A if sigma_T is lower than sigma_E; B if sigma_T exceeds sigma_E by less than 10%; C if by 10% or more. Not assessable if valid pixels < 5%.

SAR K-ARD NRB Quality Assessment — M2: Backscatter Dependence on Local Incidence Angle
==============================================================================
Product/Tile : Tile 12SUC33, acquired 2023-10-08 (12SUC33_20231008013527_K5_ES02_NRB)
Grade        : A

Ellipsoidal incidence angle                         : 23.702°
Regression slope, gamma-naught E (slope_E)          : 0.02398 dB/deg
Regression slope, gamma-naught T (slope_T)          : 0.01252 dB/deg
Change in gamma-naught T per 10° of LIA             : 0.1252 dB (threshold 0.20 dB)
Basis of grade                                      : |slope_T| is smaller than |slope_E|, and the change in gamma-naught (T) per 10 degrees of LIA (0.125 dB) is less than 0.20 dB.

Grading rule: C if |slope_T| ≥ |slope_E|. Otherwise, A if the change in gamma-naught (T) per 10° of LIA is less than 0.20 dB; B if it is 0.20 dB or greater. Not assessable if valid pixels < 5%.
