Detailed Description

An iterator class for MeasurementSets.

Intended use:

Public interface

Prerequisite

MeasurementSet

Etymology

MSIter stands for the MeasurementSet Iterator class.

Synopsis

An MSIter is a class to traverse a MeasurementSet in various orders. It automatically adds four predefined sort columns to your selection of sort columns (see constructor) so that it can keep track of changes in frequency or polarization setup, field position and sub-array. Note that this can cause iterations to occur in a different way from what you would expect, see examples below. MSIter implements iteration by time interval for the use of e.g., calibration tasks that want to calculate solutions over some interval of time. You can iterate over multiple MeasurementSets with this class.

Example

// The following code iterates by by ARRAY_ID, FIELD_ID, DATA_DESC_ID and
// TIME (all implicitly added columns) and then by baseline (antenna pair),
// in 3000s intervals.
MeasurementSet ms("3C273XC1.ms"); 
Block<int> sort(2);
sort[0] = MS::ANTENNA1;
sort[1] = MS::ANTENNA2;
Double timeInterval = 3000;
MSIter msIter(ms,sort,timeInteval);
for (msIter.origin(); msIter.more(); msIter++) {
// print out some of the iteration state
cout << msIter.fieldId() << endl;
cout << msIter.fieldName() << endl;
cout << msIter.dataDescriptionId() << endl;
cout << msIter.frequency0() << endl;
cout << msIter.table().nrow() << endl;
process(msIter.table()); // process the data in the current iteration
}
// Output shows only 1 row at a time because the table is sorted on TIME
// first and ANTENNA1, ANTENNA2 next and each baseline occurs only once per 
// TIME stamp. The interval has no effect in this case.

Example

// The following code iterates by baseline (antenna pair), TIME, and,
// implicitly, by ARRAY_ID, FIELD_ID and DATA_DESC_ID in 3000s
// intervals.
MeasurementSet ms("3C273XC1.ms"); 
Block<int> sort(3);
sort[0] = MS::ANTENNA1;
sort[1] = MS::ANTENNA2;
sort[2] = MS::TIME;
Double timeInterval = 3000;
MSIter msIter(ms,sort,timeInteval);
for (msIter.origin(); msIter.more(); msIter++) {
// print out some of the iteration state
cout << msIter.fieldId() << endl;
cout << msIter.fieldName() << endl;
cout << msIter.dataDescriptionId() << endl;
cout << msIter.frequency0() << endl;
cout << msIter.table().nrow() << endl;
process(msIter.table()); // process the data in the current iteration
// Now the output shows 7 rows at a time, all with identical ANTENNA1
// and ANTENNA2 values and TIME values within a 3000s interval.
}

Motivation

This class was originally part of the VisibilityIterator class, but that class was getting too large and complicated. By splitting out the toplevel iteration into this class the code is much easier to understand. It is now also available through the ms tool.

To Do

multiple observatories in a single MS are not handled correctly (need to sort on observation id and check observatory name to set position frame)

Constructor & Destructor Documentation

casacore::MSIter::MSIter ( )

Default constructor - useful only to assign another iterator later.

Use of other member functions on this object is likely to dump core.

casacore::MSIter::MSIter	(	const MeasurementSet &	ms,
		const Block< Int > &	sortColumns,
		Double	timeInterval = `0`,
		Bool	addDefaultSortColumns = `True`,
		Bool	storeSorted = `True`
	)

Construct from MS and a Block of MS column enums specifying the iteration order, if none are specified, ARRAY_ID, FIELD_ID, DATA_DESC_ID, and TIME iteration is implicit (unless addDefaultSortColumns=False) These columns will be added first if they are not specified.

An optional timeInterval can be given to iterate through chunks of time. The default interval of 0 groups all times together. Every 'chunk' of data contains all data within a certain time interval and with identical values of the other iteration columns (e.g. DATA_DESCRIPTION_ID and FIELD_ID). See the examples above for the effect of different sort orders.

The storeSorted parameter determines how the resulting SORT_TABLE is managed. If storeSorted is true then the table will be stored on disk; this potentially allows its reuse in the future but has also been shown to be a problem when the MS is being read in parallel. If storeSorted is false then the SORTED_TABLE is constructed and used in memory which keeps concurrent readers from interfering with each other.

casacore::MSIter::MSIter	(	const Block< MeasurementSet > &	mss,
		const Block< Int > &	sortColumns,
		Double	timeInterval = `0`,
		Bool	addDefaultSortColumns = `True`,
		Bool	storeSorted = `True`
	)

Same as above with multiple MSs as input.
