1.3.2.0 msmetadata.open

NRAO Home > CASA > CASA Toolkit Reference Manual

msmetadata.open - Function

1.3.2 Attach the MS metadata tool to the specified MS

Description

Attach this tool to the specified MS. This method runs a few basic MS validation tests, and if any of these fail (which indicates that the MS is invalid), an error occurs and the tool is not attached to the MS. Note that it is ultimately the user’s responsibility to ensure that the MS is valid. Running the methods of this tool on an invalid MS may result in incorrect results or even a crash of CASA. Such invalidities include any MS subtable not having appropriate information (eg, an OBSERVATION subtable not having enough rows to account for all the OBSERVATION_IDs in the main table).

                msmd.done()
