Example
The flag version files are copies of the FLAG column of a
Measurement Set. They can be restored to the data set to obtain
a previous flag version. On running importasdm, a flag
version called ’Original’ is produced by default. It is recommended to
save a flagversion at the beginning or after serious editing.

vis -- Name of input visibility file
default: none. example: vis=’ngc5921.ms’

’restore’: will place the specified flag file into vis
