16 calstat ---- Calculates statistical information on a calibration table 

17 

18  

19 This task returns statistical information about a column in a 

20 calibration table. The following values are computed: mean value, sum 

21 of values, sum of squared values, median, median absolute deviation, 

22 quartile, minimum, maximum, variance, standard deviation, root mean 

23 square. 

24 

25 --------- parameter descriptions --------------------------------------------- 

26 

27 caltable Name of input calibration table 

28 Default: '' 

29  

30 Example: vis='ggtau.1mm.amp.gcal' 

31 axis Which data to analyze. 

32 Default: 'amplitude' 

33 Options: 'amp', 'amplitude', 'phase', 'real', 

34 'imag', 'imaginary'. Also, the name of any real 

35 valued MS column can be given, e.g. TIME, 

36 POLY_COEFF_AMP, REF_ANT, ANTENNA1, FLAG, ... 

37  

38 Note: the phase of a complex number is in 

39 radians in the range [-pi; pi]. 

40 datacolumn Which data column to use if axis is 'amp', 'amplitude', 'phase', 'real', 'imag' or 'imaginary'. 

41 Default: 'gain'
