19 These flag version files are copies of the flag column for a 

20 measurement set. They can be restored to the data set to get 

21 back to a previous flag version. On running importvla, a flag 

22 version call 'Original' is automatically produced.

40 The flag version files are copies of the FLAG column of a 

41 Measurement Set. They can be restored to the data set to obtain 

42 a previous flag version. On running importasdm, a flag 

43 version called 'Original' is produced by default. It is recommended to 

44 save a flagversion at the beginning or after serious editing. 

45  

46 Keyword arguments: 

47 vis -- Name of input visibility file 

48 default: none. example: vis='ngc5921.ms' 

49  

50 mode -- Flag version operation 

51 default: 'list': it will list in the logger the existing flag versions of the MS. 

52 This option will also return by default a dictionary containing the 

53 name of the MS, the name of the flag version and the comment. This 

54 information is taken from the FLAG_VERSION_LIST file inside the 

55 .flagversions directory. 

56  

57 'save': will save the FLAG column from vis to a specified flag file. If the name given 

58 in versionname already exists, the task will give a warning and rename it 

59 to a name with a suffix '.old.timestamp'. The respective entry in FLAG_VERSION_LIST 

60 will also be updated. 

61  

62 'restore': will place the specified flag file into vis 

63  

64 'delete': will delete specified flag file 

65  

66 'rename': will rename a specified flag file 

67  

68 versionname -- Flag version name 

69 default: none; example: versionname='original_data' 

70 No imbedded blanks in the versionname 

71  

72 comment -- Short description of a versionname, when mode is 'save' or 'rename' 

73 default: ''; example: comment='Clip above 1.85' 

74 comment = versionname 

75  

76 oldname -- When mode='rename', the flag file to rename 

77  

78 merge -- Merge operation 

79 Options: 'or','and', but not recommended for now.
