Notes: This table defines the state parameters for a particular data record as they refer to external loads, calibration sources or references, and also characterizes the observing mode of the data record, as an aid to defining the scheduling heuristics. It is indexed directly via the STATE_ID identifier in the MAIN table.
SIG
If SIGand REF are both together false there is blanking.
REF
True for a generic reference phase in the switching scheme. Example: REF is TRUE when on chopper or any load, or when on a phase reference calibrator in the Fast Switching observing mode.
CALLOAD_NUM
Calibration load number. The CALDEVICE table contains the temperature of the loads The CALDEVICE table is referenced via the primary keys in the MAIN and SYSCAL tables and this item CALLOAD_NUM is relevant only auto-correlation measurements i.e. when CORRELATION_MODE in the CONFIG_DESCRIPTIONtable is 1.
WEIGHT
Relative weight of switch state for final processing.
SUBINTEG_NUM
Used to enumerate sub-integrations (from 1 for the first sub-integration of an integration); implicitly associated to the number of sub-integration this being enumerated relative the integration.
OBS_MODE
Observing mode.  .
Note that here OBS is not attached to the concept of OBSERVATION given in the ALMA glossary! Reserved attributes are TBD.
OBS_INTENT
Intent of the sub-integration. Reserved attributes are TBD. Examples: FOCUS, PHASEREF, POINTING. Not required to be unique.   .
FLAG_ROW
True if the row does not contain valid data. Does not imply flagging in MAIN
