Prerequisite

• MSObservation
• ArrayColumn
• ScalarColumn

Etymology

MSObservationColumns stands for MeasurementSet Observation Table columns.

Synopsis

This class provides access to the columns in the MSObservation Table, it does the declaration of all the Scalar and ArrayColumns with the correct types, so the application programmer doesn't have to worry about getting those right. There is an access function for every predefined column. Access to non-predefined columns will still have to be done with explicit declarations. See MSColumns for an example.

Motivation

See MSColumns for the motivation.

void casacore::MSObservationColumns::setEpochRef	(	MEpoch::Types	ref,
		Bool	tableMustBeEmpty = True
	)

set the epoch type for the TIME_RANGE & RELEASE_DATE columns.

Tip: In principle this function can only be used if the table is empty, otherwise already written values may thereafter have an incorrect reference, offset, or unit; However, it is possible that part of the table gets written before these values are known; In that case the reference, offset, or units can be set by using a False tableMustBeEmpty argument;
