msmetadata.nbaselines - Function

1.3.2 Get the number of baselines represented in the main MS table.


Description

Get the number of unique baselines (antenna pairs) represented in the main MS table. This can, in theory, be less than n*(n-1)/2 (n being the number of antennas in the ANTENNA table), if data for certain baselines are not included in the main MS table. Autocorrelation ”baselines” are included in this count if ac=True.

Arguments

ac

    msmd.open("my.ms")  
    number_of_baselines = msmd.nbaselines()  
    number_of_baselines_including_ac = msmd.nbaselines(True)  
    msmd.done()
