Example

 
 
       A multi-measurement set (MMS) is an MS that has been split into sub-MSs.  
       An MMS contains a reference MS in the top directory and the sub-MSs are  
       located in a directory called SUBMSS inside the MMS directory.  
       Example of a MS that was partitioned in the ’scan’ axis using the task partition:  
 
       > ls ngc5921.mms  
         ANTENNA           FLAG_CMD     POLARIZATION  SPECTRAL_WINDOW  table.dat  
         DATA_DESCRIPTION  HISTORY      PROCESSOR     STATE            table.info  
         FEED              OBSERVATION  SORTED_TABLE  SUBMSS           WEATHER  
         FIELD             POINTING     SOURCE        SYSCAL  
 
       > ls ngc5921.mms/SUBMSS/  
         ngc5921.0000.ms/  ngc5921.0002.ms/  ngc5921.0004.ms/  ngc5921.0006.ms/  
         ngc5921.0001.ms/  ngc5921.0003.ms/  ngc5921.0005.ms/  
 
       The task lists the following properties of a multi-MS or MS:  
       sub-MS name, scan, spw list, list of number of channels per spw,  
       number of rows for each scan and the size in disk. Example of logger output:  
 
        Sub-MS          Scan  Spw      Nchan    Nrows   Size  
        ngc5921.0000.ms  1    [0]      [63]     4509    11M  
        ngc5921.0001.ms  2    [0]      [63]     1890    6.4M  
        ngc5921.0002.ms  3    [0]      [63]     6048    13M  
        ngc5921.0003.ms  4    [0]      [63]     756     4.9M  
        ngc5921.0004.ms  5    [0]      [63]     1134    6.4M  
        ngc5921.0005.ms  6    [0]      [63]     6804    15M  
        ngc5921.0006.ms  7    [0]      [63]     1512    6.4M

       vis -- Name of multi-MS or normal MS.  
              default: ’’.  
              example: vis=’pScan.mms’  
 
       createdict -- Create and return a dictionary containing scan summaries of each  
                     sub-MS.  
              default: False  
 
              If set to True, the returned dictionary will contain information from  
              ms.getscansummary() and ms.getspectralwindowinfo(), with the addition of an  
              index as the top key and the sub-MS name.  
              Example:  
 
            {0: {’MS’: ’ngc5921.0000.ms’,  
                 ’scanId’: {1: {’nchans’: array([63], dtype=int32),  
                                ’nrows’: 4509,  
                                ’spwIds’: array([0], dtype=int32)}},  
                 ’size’: ’11M’},  
             1: {’MS’: ’ngc5921.0001.ms’,  
                 ’scanId’: {2: {’nchans’: array([63], dtype=int32),  
                                ’nrows’: 1890,  
                                ’spwIds’: array([0], dtype=int32)}},  
                 ’size’: ’6.4M’}}  
 
       listfile -- Name of ASCII file to save output to. If empty, it will
