Notes: This table holds summary information for the back-end processing devive used to generate the basic data in the MAIN  and PWVM  table. Such devices include correlators, radiometers, spectrometers, pulsar-timers, amongst others.
TYPE
Processor type; reserved keywords include CORRELATOR1  - interferometric correlator, SPECTROMETER2  - single-dish correlator, RADIOMETER3  - generic detector/integrator, PULSAR-TIMER4  - pulsar timing device)
NB: ALMA would use the reserved type “RADIOMETER” (generic detector/integrator) for the radiometers In MS2 PROCESSOR_IDis referenced exclusively5 in the MAIN.  
SUB_TYPE
Index used in specialized sub-table named as subtype_type_mode which contains time independent processor information applicable to the current data or rcdata record (e.g. a JIVE_CORRELATOR sub-table). Time-dependent information for each device family is contained in other tables, dependent on the device type.
TYPE_ID
Index used in specialized sub-table named as subtype_type_mode containing information on the processor mode applicable to the current data record.
(eg VESPA_SPECTROMETER_MODE sub-table).
MODE_ID
Index used in a specialized sub-table name as subtype_type, comtaining information on the processor mode applicable to the current data record. (e.g. a ALMA_SPECTROMETER_MODE sub-tables).
PASS_ID
Pass identifier. This is used to distinguish data records produced by multiple passes through the same device, where this is possible (eg VLBI correlators). Used as an index into the associated table containing pass information.
FLAG_ROW
Row flag. True if data in the row is not valid, but does not imply flagging in the MAIN  or PWVM .
