Notes: This table is dedicated to the raw data originating from the radiometers to monitor the amount of precipitable water vapor in the pointing direction of each antenna and from the astronomical receivers to monitor eg their stability. This table is very similar to the MAIN table except that the data are directly present. These data may not be synchronized with the correlated astronomical data.


AEDF_VERSION EDF revision number, expressed as major_revision.minor_revision.

TIME Mid-point (not centroid) of data interval.

CONFIG_DESCRIPTION_ID Configuration descriptor identifier (> 0) providing a direct index into the CONFIG_DESCRIPTION sub-table row number. Note that two or more sub-arrays cannot refer to the same CONFIG_DESCRIPTION_ID identifier. Note also that in this CONFIG_DESCRIPTION table PROCESSOR_ID must be indexed for a processor of type RADIOMETER and that CORRELATION_MODE must have a value Ncm=1. FIELD_ID Field identifier (> 0)

INTERVAL Data sampling interval. This is the nominal data interval, it does not include the effects of bad data or partial integration. EXECUTE_ID This provides access to a row number in the EXECUTE_SUMMARY table. This meta coordinate defines the data-base in term of an implicit collection of data blocks.

SCAN_NUMBER SCAN (ref. ALMA glossary) number. Enumeration relative to the Executing Block. This item is not mandatory. It should be used if the data are synchronized with the data from the correlator.

SUBSCAN_NUMBER SUBSCAN (ref. ALMA glossary) number. This item is not mandatory. It should be used if the data are synchronized with the data from the correlator.

INTEG_NUMBER INTEGRATION (ref. ALMA glossary) number.This item is not mandatory. It should be used if the data are synchronized with the data from the correlator. STATE_ID State identifier (> 0).

UVW Antenna-based uvw coordinates for the Na antennas. This is defined at the centroid time TIME_CENTROID .

EXPOSURE Effective duration of an INTEGRATION (or a SUBINTEG_NUM in the STATE table is > 0).

TIME_CENTROID Time stamp reflecting the average time the non-blanked data was integrated.

FLOAT_DATA Total power data.

FLAG_ANT Unsigned long int (4-bytes) vector. Each bit corresponds to a specified flagging condition ( e.g. 22 = pointing, 26 = shadowing, ...). When different from zero all data concerning the antenna is affected.

FLAG_POL Unsigned long int (4-bytes) vector . When different from zero all data concerning the polarization and antenna is invalid.
