Field | Description | Type | Null | Limits | Size | Key | Default | Authority | Source |
---|---|---|---|---|---|---|---|---|---|
ID | This is a unique, numerical ID assigned by the database to each record in this table. | INT(10) unsigned auto_increment | Not Null | Primary Key | db server | ||||
OBSERVATION_ID | The observation id these statistics apply to. | VARCHAR(25) | Not Null | HiMosMerge | |||||
FROST_FOUND | If set to yes, then the statistics indicate frost is in the image. | ENUM("NO","YES") | Not Null | HiMosMerge | |||||
INCIDENCE_ANGLE_USED | Incidence angle used in the computation of the photometrically corrected scene brightness. This incidence angle used here may not necessarily be the same as the angle found in the Observation_Geometry. The value will be modified for high latitude observations to compensate for atmospheric haze effects. | FLOAT | HiMosMerge | ||||||
REDUCE_FACTOR | An integer value that defines the NXN box size of the reduced image used to acquire ratio and brightness statistics. | INT(4) unsigned | HiMosMerge | ||||||
BG_PHOTO_CORRECTED | BG maximum value that has photometric correction applied | FLOAT | HiMosMerge | ||||||
BG_RED_RATIO_THRESHOLD | BG/RED ratio threshold value | FLOAT | HiMosMerge | ||||||
BG_PHOTO_CORRECTED_THRESHOLD | Photometrically-corrected BG threshold value | FLOAT | HiMosMerge | ||||||
INCIDENCE_ANGLE_THRESHOLD | Incidence angle threshold value for when only the BG/RED ratio value is used in determining if ice/frost is present | FLOAT | HiMosMerge | ||||||
