Notes: This table holds summary information for the back-end processing device used to generate the basic data in the MAIN and TOTAL_POWER_MONITORING table. Such devices include correlators, radiometers, spectrometers amongst others. The PROCESSOR_ID identifier is indexed in the CONFIG_DESCRIPTION table.
TYPE
Processor type; reserved keywords include:
CORRELATOR1  - interferometric correlator,
SPECTROMETER2  - single-dish correlator,
RADIOMETER3  - generic detector/integrator,
Note that ALMA uses the reserved type “RADIOMETER” (generic detector/integrator) for the data originating from the radiometers to monitor the atmosphere and also for the total power detected over the band, directly from the astronomical receivers.
SUB_TYPE
Index used in specialized sub-table named as subtype_type which contains time independent processor information applicable to the current data record (e.g. a ALMA_CORRELATOR sub-table).
The time-dependent information for each device family is contained in other tables, dependent on the device type.
MODE_ID
Identifier used in a specialized sub-table name as subtype_type_mode, containing information on the processor mode applicable to the current data record. (e.g. a ALMA_CORRELATOR_MODE sub-table).
FLAG_ROW
Row flag. True if data in the row is not valid, but does not imply flagging in the MAIN or TOTAL_POWER_MONITORING.
