origin_error Columns

ColumnName | Domain | Datatype | NULL | Definition
orid |  | NUMBER(15, 0) | NO | Origin identification. Each origin is assigned a unique positive integer which identifies it in the database. The orid is used to identify one of the many hypotheses of the actual location of the event
sxx |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
syy |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
szz |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
stt |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
sxy |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
sxz |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
syz |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
stx |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively. These attributes (together with sdobs, ndef and dattype) provide all the information necessary to construct the K-dimensional (K=2, 3, 4) confidence ellipse or ellipsoids at any confidence limit desired
sty |  | NUMBER(7, 3) | YES | Elements of the covariance matrix for the location defined by orid. The covariance matrix is symmetric (and positive definite) so that sxy = syx, etc., (x, y, z, t) refer to latitude, longitude, depth and origin time, respectively.
