35 A multi-measurement set (MMS) is an MS that has been split into sub-MSs. 

36 An MMS contains a reference MS in the top directory and the sub-MSs are 

37 located in a directory called SUBMSS inside the MMS directory. 

38 Example of a MS that was partitioned in the 'scan' axis using the task partition: 

39  

40 > ls ngc5921.mms 

41 ANTENNA FLAG_CMD POLARIZATION SPECTRAL_WINDOW table.dat 

42 DATA_DESCRIPTION HISTORY PROCESSOR STATE table.info 

43 FEED OBSERVATION SORTED_TABLE SUBMSS WEATHER 

44 FIELD POINTING SOURCE SYSCAL 

45  

46 > ls ngc5921.mms/SUBMSS/ 

47 ngc5921.0000.ms/ ngc5921.0002.ms/ ngc5921.0004.ms/ ngc5921.0006.ms/ 

48 ngc5921.0001.ms/ ngc5921.0003.ms/ ngc5921.0005.ms/ 

49  

50 The task lists the following properties of a multi-MS or MS: 

51 sub-MS name, scan, spw list, list of number of channels per spw, 

52 number of rows for each scan and the size in disk. Example of logger output: 

53  

54 Sub-MS Scan Spw Nchan Nrows Size 

55 ngc5921.0000.ms 1 [0] [63] 4509 11M 

56 ngc5921.0001.ms 2 [0] [63] 1890 6.4M 

57 ngc5921.0002.ms 3 [0] [63] 6048 13M 

58 ngc5921.0003.ms 4 [0] [63] 756 4.9M 

59 ngc5921.0004.ms 5 [0] [63] 1134 6.4M 

60 ngc5921.0005.ms 6 [0] [63] 6804 15M

64 ------- Detailed description of keyword arguments ------- 

65 vis -- Name of multi-MS or normal MS. 

66 default: ''. 

67 example: vis='pScan.mms' 

68  

69 createdict -- Create and return a dictionary containing scan summaries of each 

70 sub-MS. 

71 default: False 

72  

73 If set to True, the returned dictionary will contain information from 

74 ms.getscansummary() and ms.getspectralwindowinfo(), with the addition of an 

75 index as the top key and the sub-MS name. 

76 Example: 

77  

78 {0: {'MS': 'ngc5921.0000.ms', 

79 'scanId': {1: {'nchans': array([63], dtype=int32), 

80 'nrows': 4509, 

81 'spwIds': array([0], dtype=int32)}}, 

82 'size': '11M'}, 

83 1: {'MS': 'ngc5921.0001.ms', 

84 'scanId': {2: {'nchans': array([63], dtype=int32), 

85 'nrows': 1890, 

86 'spwIds': array([0], dtype=int32)}}, 

87 'size': '6.4M'}} 

88  

89 listfile -- Name of ASCII file to save output to. If empty, it will 

90 list on the logger/terminal. 

91 default: '' 

92 example: listfile='pscan.txt'
