seismic_header.identifier
The name of the header information.
instance_create_date (O: TIMESTAMP)
e_and_p_data.instance_create_date
This is the date that this instance was created. This date is defined by the source if imported, or is the date the instance is created if a new instance.
last_updated (O: TIMESTAMP)
e_and_p_data.last_updated
This is the date that this instance was last updated. This value should be updated when any part of this instance is altered (except for inverse relationships).
seismic_geometry_set_s (FSK, M: CHAR VARYING(19))
seismic_header.seismic_geometry_set
Defines the acquisition geometry which is represented by this header information.
Defines a foreign key to table geophysical_geometry_set.
description (O: CHAR VARYING(2000))
e_and_p_data.description
A remark or comment about the instance.
instance_creator (O: CHAR VARYING(80))
e_and_p_data.instance_creator
This is the person, company or application that created this instance. This identifies the party responsible for loading this instance.
last_updated_by (O: CHAR VARYING(80))
e_and_p_data.last_updated_by
This records the person or application making the update to this instance.
seismic_data_header_sl (O: CHAR VARYING(16))
seismic_header.seismic_data_header
Defines values at nodes in a grid. If no "grid use" attributes are defined then the values will semantically identify each node. For prestack "trace" data this would typically represent properties such as "source event uid", "receiver uid" (or "channel uid"), "bin point index" and/or "bin line index".
source (O: CHAR VARYING(80))
e_and_p_data.source
The provider of this instance, which is usually a data provider for imported/purchased data. If this instance is provided by POSC, then this attribute must be "POSC".
activity_s (FSK, O: CHAR VARYING(19))
process_data.activity
Defines the activity which created this instance.
Defines a foreign key to table activity.
use_acquisition_grid_s (FSK, O: CHAR VARYING(19))
seismic_header.use_acquisition_grid
Defines the geometry set that defines the semantics of the grid utilized by seismic data header. For example, if the grid specifies "source event uid" then it is implied that the source event uid grid of the referenced geometry set is being used.
Defines a foreign key to table geophysical_geometry_set.
use_processing_grid_s (FSK, O: CHAR VARYING(19))
seismic_header.use_processing_grid
Defines the binset that specifies the semantics of the grid utilized by seismic data header.
Defines a foreign key to table geophysical_processing_grid.
