Motivation See MSColumns for the motivation. If not an AipsError is thrown as such an argument will never match any row of the Table. The tolerance is the maximum allowed distance between the two positions and the supplied Quantum must have dimensions of length. This is checked when compiled in debug mode and an AipsError exception is thrown if the dimensions are wrong. Returns -1 if no match could be found.
Flaged rows can never match.
If tryRow is non-negative, then that row is tested to see if it matches before any others are tested. Same as the previous function except that the antenna name must also match. This class provides access to the columns in the MSAntenna 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.
