Flags

FLAG_ROW

Bool The row flag
Notes: This table gives the set of Executing Blocks associated to each Scheduling Block; at the same time it gives the list of Scheduling Block actually used. It is indexed via the identifier EXECBLOCK_IDdirectly from the HISTORY and as a secondary index, from the TOTAL_POWER_MONITORING and MAIN tables.
NUM_ANTENNA
Number of antennas Na (indicative) for the antenna configuration.
N.B.: It must be understood that this number does not necessarily correspond to the number of rows in the ANTENNA table; it may be smaller but never larger. This number does not correspond neither to Na in the CONFIG_DESCRIPTION table.
TELESCOPE_NAME
Name of the telescope, ALMA. 
TELESCOPE_POSITION
Telescope center position.
CONFIG_NAME
String type to support names with current instruments (TBD).
ANTENNA_ID_SET
Collection: set of antenna identifiers ANTENNA_ID giving the ensemble of antennas which belong to the current array configuration. These identifiers do not need to be given in a specific order but obviously the members in this collection must be unique.
Note that if there are subarrays, the subsets of antennas forming these subarrays are specified in the CONFIG_DESCRIPTION table. The present collection does not imply that all its members are cross-correlated. Note that the radiometric data from e.g. different spectral subarrays may be put together to build the atmospheric phase structure function.
BASE_RANGE
Baseline range (minimum, maximum).
N.B.: This range gives the extent over which the phase structure function is sampled.
BASE_RMS
rms along the minor and major axis in the baseline distribution at the zenith. This provides one characteristic for the current array configuration.
BASE_PA
Position angle in the distribution of baselines.
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 SB execution.
OBSERVER_NAME
Name of the observer.
OBSERVING_LOG
Name of the observing log.
OBSERVING_MODE
Observing mode, e.g. singleField, mosaic
The definition of the observing modes at the level of a ShedulingBlock are TBD.
PROJECT
Project reference (TBD)  
EXECBLOCK_NUM
ExecBlock number in the scheduled block. This number is qualified within the context of a project and a scheduling block.
SCHEDULE_ID
Scheduling Block identifier. Not required to be unique.
EXECUTEE_INTENT
Intent given for the execution of the SB. When the execution of a given SB is repeated the intent would be e.g. increaseUvCoverage, monitorVariability, increaseStoN etc... Not required to be unique.
EXECUTE_SCRIPT
The same file name, if the same script is used, may be given here if what has been scheduled is exactly what has been executed. Not required to be unique. Each Executing Block has to be notified with one row in this table.
It is indexed directly from the MAIN table for a straightforward segmentation of whole data base into data blocks.
EXECBLOCK_ID is used for data selection to define an Observation Unit (see the OBSERVATION_UNIT sub-table).
RELEASE_DATE
Date the Executing Block becomes public.
FLAG_ROW
True if the row does not contain valid data; does not imply flagging in the MAIN table.

Remark:
CONFIG_NAME provides the state of the antenna configuration during the execution of a Scheduling Block, even if not all antennas are used for that execution. The actual description of a sub-array is given by an ANTENNA_ARRAY collection in the CONFIG_DESCRIPTION table. CONFIG_NAME allows to discriminate observations obtained while the array was in one or several array configurations. If the plan is that ALMA will be in continuous reconfiguration, then it will be quite common to have multi-configuration projects. CONFIG_NAME takes clearly its importance in this context. The set of antenna idenfiers in the collection ANTENNA_ID_SET is given here to fully describe the antennas defining the antenna configuration.
Note that this table must contains as many rows as there were executions of Scheduling Blocks in the project, i.e. sum i=1i=NSBNXBi.
SCHEDULE_ID and EXECUTE_SCRIPT are not required to be unique, as it would be the case when a SB and an EXECUTE_SCRIPT are repeated.
Sub-arrays operating asynchroneously must appear with different EXECUTE_SCRIPT.
