Notes: This table stores summary information for each scan. This table plays the role of associating a certain number of rows in the Main table, the nature of this association being reflected by the scan intent.
EXECBLOCK_ID
Identifier pointing to one row in the EXECBLOCK_SUMMARY table.
TIME
Time mid-point interval. The same reference used for the TIME column in the MAIN must be used.
INTERVAL
Time interval. This is the difference between the end and begin TIME of the scan.
SCAN_INTENT
Scan intent. Since this is the unique location in the SDM where this item is present, this SCAN_SUMMARY table is mandatory.
SCAN_NUMBER
Scan number as enumerated during the execution of the SchedulingBlock.
NUM_SUBSCAN
Number of subscans in the scan
NUM_FIELD
Number of fields observed in the scan. Note that several fields may be observed simultaneously when activities of subarrays are coordinated in time.
FIELD_NAME
Name(s) of the field, as specified during the execution of the Scheduling Block.
SUBSCAN_NUM_SET
Collection of SUBSCAN_NUM numbers for this scan in the data set. These do not need to be given in a specific order but obviously their values must be unique.
FLAG_ROW
True if data in this row are invalid, else False. Does not imply flagging in the MAIN.
