Synopsis

Member Description

SubMS(String& theMS)

SubMS(MeasurementSet& ms)

construct from an MS

~SubMS()

void setMS(MeasurementSet& ms)

Change or Set the MS this MSSelector refers to.

void selectSpw(Vector<Int> spw, Vector<Int> nchan, Vector<Int> start, Vector<Int> step, Bool averchan=True)

select spw and channels for each spw...

void selectSource(Vector<Int> fieldid)

select Time and time averaging or regridding void selectTime();

Select source or field

void selectAntenna(Vector<Int>& antennaids, Vector<String>& antennaSel)

Select Antennas to split out

void selectTime(Double timeBin=-1.0, String timerng="")

select time parameters

Bool makeSubMS(String& submsname, String& whichDataCol)

void selectSource(Vector sourceid);

Method to set if a phase Center rotation is needed void setPhaseCenter(Int fieldid, MDirection& newPhaseCenter);

Method to make the subMS

MeasurementSet* makeScratchSubMS(String& whichDataCol, Bool forceInMemory=False)

Method to make a scratch subMS and even in memory if posssible Useful if temporary subselection/averaging is necessary It'll be in memory if the basic output ms is less than half of memory reported by HostInfo unless forced to by user...

static MeasurementSet* setupMS(String msname, Int nchan, Int npol, String telescop, Int obstype=0)

This setup a default new ms Can be called directly as its not dependent on any private variable
