Example
This task returns statistical information about a column in a calibration table.
The following values are computed: mean value, sum of values, sum of squared values,
median, median absolute deviation, quartile, minimum, maximum,
variance, standard deviation, root mean square.
Keyword arguments:
caltable -- Name of input calibration table
default: ’’, example: vis=’ggtau.1mm.amp.gcal’
axis -- Which data to analyze. The possible values are ’amp’, ’amplitude’, ’phase’,
’real’, ’imag’, ’imaginary’. Also, the name of any real valued MS column can be
given, e.g. TIME, POLY_COEFF_AMP, REF_ANT, ANTENNA1, FLAG, ...
default: ’amplitude’
axis=’gain’
The phase of a complex number is in radians in the range [-pi; pi[.
datacolumn -- Which data column to use if axis is ’amp’, ’amplitude’,
’phase’, ’real’, ’imag’ or ’imaginary’.
default: ’gain’
datacolumn=’gain’
useflags -- Take MS flags into account (not implemented, this parameter
has no effect!)
default: False
useflag=False
useflag=True
If useflags=False, flagged values are included in the statistics.
If useflags=True, any flagged values are not used in the statistics.
