| Enable list, save, restore, delete and rename flag version files.
| |
| | |
| | |
| These flag version files are copies of the flag column for a
| |
| measurement set. They can be restored to the data set to obtain
| |
| a previous flag version. On running importvla, a flag
| |
| version call 'Original' is automatically produced. It is wise to
| |
| save a flagversion at the beginning or after serious editing.
