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
------- Detailed description of 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’: ’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
list on the logger/terminal.
default: ’’
example: listfile=’pscan.txt’
