DM Attributes 
Attribute/Logical Rolename  Domain  Datatype  NULL  Definition 
key(PK)    NUMERIC(8, 0)  NO  This attribute denotes a unique identifier for a decimation 
name    VARCHAR(80)  YES  Descriptive name 
samprate    FLOAT  NO  Sampling rate. This attribute is the sample rate in samples/second 
factor    NUMERIC(8, 0)  NO  The decimation factor. When this number of samples are read in, one final sample comes out. The output sample rate can be calculated by dividing samprate by the decimation factor 
offset    NUMERIC(8, 0)  YES  This field determines which sample is chosen for use. The value of this field has to be greater than or equal to zero, but less than the decimation factor 
delay    FLOAT  YES  The estimated pure delay for the stage 
correction    FLOAT  NO  The time shift applied to the time tag due to delay at this stage of the filter; a negative number indicating the amount of time added to the former time tag. The actual delay is difficult to estimate, and the correction applied neglects dispersion.This field allows to know how much correction was used, in case a more accurate correction is to be applied later. A zero here implies no correction was done 
lddate    DATE  YES  Load date. Date and time that the record was created or last modified, in Oracle date datatype
