List the summary of a multi-MS data set in the logger or in a file
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 'split' in two scans using the task partition:
> ls pScan.mms/
SUBMSS/ table.dat table.info
> ls pScan.mms/SUBMSS/
pScan.0000.ms/ pScan.0001.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
pScan.0000.ms 31 [ 0 1 2 3 4] [64 64 64 64 64] 8640 42M
pScan.0001.ms 30 [ 0 1 2 3 4] [64 64 64 64 64] 8544 42M
Keyword arguments:
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': 'pScan.0000.ms',
'scanId': {31: {'nchans': array([64, 64, 64, 64, 64]),
'nrows': 8640,
'spwIds': array([ 0, 1, 2, 3, 4])}},
'size': '42M'},
1: {'MS': 'pScan.0001.ms',
'scanId': {30: {'nchans': array([64, 64, 64, 64, 64]),
'nrows': 8544,
'spwIds': array([ 0, 1, 2, 3, 4])}},
'size': '42M'}}
listfile -- Name of ASCII file to save output to. If empty, it will
list on the logger/terminal.
default: ''
example: listfile='pscan.txt'
