16 clearcal ---- Re-initializes the calibration for a visibility data set 

17 

18  

19 Clearcal reinitializes the calibration columns in a measurement 

20 set. Specificially, it will set the MODEL_DATA column (if present) to 

21 unity in total intensity and zero in polarization, and it will set the 

22 CORRECTED_DATA column to the original (observed) DATA in the DATA 

23 column. Use the field and spw parameters to select which data to 

24 initialize. If the dataset does not yet have the scratch columns, 

25 they will be created (MODEL_DATA only if addmodel=True) and initilized 

26 for the whole dataset (field, spw, and intent will be ignored in this 

27 case). 

28 

29 --------- parameter descriptions --------------------------------------------- 

30 

31 vis Name of input visibility file (MS) 

32 Default: none 

33  

34 Example: vis='ngc5921.ms' 

35 field Select field using field id(s) or field name(s) 

36 default: '' (all fields) 

37  

38 Use 'go listobs' to obtain the list id's or 

39 names. If field string is a non-negative integer, 

40 it is assumed a field index, otherwise, it is 

41 assumed a field name. 

42  

43 Examples: 

44 field='0~2'; field ids 0,1,2 

45 field='0,4,5~7'; field ids 0,4,5,6,7 

46 field='3C286,3C295'; field named 3C286 and 

47 3C295 

48 field = '3,4C*'; field id 3, all names 

49 starting with 4C 

50 spw Select spectral window/channels 

51  

52 Examples: 

53 spw='0~2,4'; spectral windows 0,1,2,4 (all 

54 channels) 

55 spw='<2'; spectral windows less than 2 

56 (i.e. 0,1) 

57 spw='0:5~61'; spw 0, channels 5 to 61, 

58 INCLUSIVE 

59 spw='\*:5~61'; all spw with channels 5 to 61 

60 spw='0,10,3:3~45'; spw 0,10 all channels, spw 

61 3, channels 3 to 45. 

62 spw='0~2:2~6'; spw 0,1,2 with channels 2 

63 through 6 in each. 

64 spw='0:0~10;15~60'; spectral window 0 with 

65 channels 0-10,15-60. (NOTE ';' to separate 

66 channel selections) 

67 spw='0:0~10^2,1:20~30^5'; spw 0, channels 

68 0,2,4,6,8,10, spw 1, channels 20,25,30  

69 type 'help par.selection' for more examples. 

70 intent Select observing intent 

71 default: '' (no selection by intent) 

72  

73 Example: intent='*BANDPASS*' (selects data 

74 labelled with BANDPASS intent) 

75 addmodel add MODEL_DATA along with CORRECTED_DATA? 

76 Default: False (model will not be added) 

77 Options: False|True 

78  

79 If False, it will add/reset only CORRECTED_DATA, 

80 model visibilities will then be evaluated when 

81 needed. 

82 RETURNS void
