Detailed Description

Class to interrogate an MS for metadata. Interrogation happens on demand and resulting metadata are stored for use by subsequent queries if the cache has not exceeded the specified limit. Caching of MS main table columns has been removed because the cache can be swamped by columns for large MSes, meaning that smaller data structures, which are more computationally expensive to create, aren't cached. Also, the column data is usually only needed temporarily to compute smaller data structures, and the column data is not particularly expensive to recreate if necessary. Parallel processing is enabled using openmp.

Constructor & Destructor Documentation

◆ MSMetaData() [1/2]

casacore::MSMetaData::MSMetaData	(	const MeasurementSet *const &	ms,
		const Float	maxCacheSizeMB
	)

construct an object which stores a pointer to the MS and queries the MS only as necessary.

The MeasurementSet pointer passed in should not go out of scope in the calling code until the caller has finished with this object, or else subsequent method calls on this object will result in a segmentation fault; the pointer is not copied. maxCacheSizeMB is the maximum cache size in megabytes. <=0 means do not use a cache, in which case, each method call will have to (re)query the MS. It is highly recommended to use a cache of reasonable size for the specified MS if multiple methods are going to be called.

This comment from thunter in the original ValueMapping python class.

Determine the number of polarizations for the first OBSERVE_TARGET intent.

Used by plotbandpass for BPOLY plots since the number of pols cannot be inferred

correctly from the caltable alone. You cannot not simply use the first row, because

it may be a pointing scan which may have different number of polarizations than what

the TARGET and BANDPASS calibrator will have.

const std::set<Int>& casacore::MSMetaData::getUniqueAntennaIDs ( ) const

get the unique antennas (the union of the ANTENNA_1 and ANTENNA_2 columns) from the main table

◆ getUniqueBaselines()

Matrix<Bool> casacore::MSMetaData::getUniqueBaselines ( )

std::map<Double, Double> getExposuresForTimes() const;

get the unique baselines in the MS. These are not necessarily every combination of the n(n-1)/2 possible antenna pairs, but rather the number of unique baselines represented in the main MS table, which in theory can be less than n(n-1)/2 (for example if samples for certain antenna pairs are not recorded. The returned Matrix is nAnts x nAnts in size. Pairs that are true represent baselines represented in the main MS table.

◆ setForceSubScanPropsToCache()

void casacore::MSMetaData::setForceSubScanPropsToCache ( Bool b )

inline

If True, force the subscan properties structure to be cached regardless of the stipulations on the maximum cache.

Normally, the subscan properties structure is small compared to the size of any one column that is necessary to create it, and since creating this structure can be very expensive, especially for large datasets, it is often a good idea to cache it if it will be accessed many times.
