16 hanningsmooth ---- Hanning smooth frequency channel data to remove Gibbs ringing
19 The hanningsmooth task uses the MSTransform framework underneath but
20 keeps roughly the same interface as the old hanningsmooth task.
22 This function Hanning smooths the frequency channels with a weighted
23 running average. The weights are 0.5 for the central channel and 0.25
24 for each of the two adjacent channels. The first and last channels are
25 flagged. Inclusion of a flagged value in an average causes that data
26 value to be flagged.
28 If the 'CORRECTED' data column is requested for an MS that does not
29 contain this column, it will use 'DATA' to calculate the smoothing and
30 save it to 'DATA' in the output MS.
32 WARNING: by default, all visibility columns will be smoothed.
34 --------- parameter descriptions ---------------------------------------------
36 vis Name of input visibility file
37 Default: none
39 Example: vis='ngc5921.ms'
40 outputvis Name of output visibility file
41 Default: '' (same as vis)
43 Example: outputvis='ngc5921_out.ms'
44 keepmms Create a Multi-MS as the output if the input is a
45 Multi-MS.
47 Default: True
48 Options: True|False
50 By default it will create a Multi-MS when the
51 input is a Multi-MS. The output Multi-MS will
52 have the same partition axis of the input
53 MMS. See CASA Docs for more information on
54 the MMS format.
55 field Select field using field id(s) or field name(s)
56 Default: '' (all fields)
58 Use 'go listobs' to obtain the list id's or
59 names. If field string is a non-negative integer,
60 it is assumed a field index, otherwise, it is
61 assumed a field name.
63 Examples:
64 field='0~2'; field ids 0,1,2
65 field='0,4,5~7'; field ids 0,4,5,6,7
66 field='3C286,3C295'; field named 3C286 and
67 3C295
68 field = '3,4C\*'; field id 3, all names
69 starting with 4C
70 spw Select spectral window/channels
71 Default: ''=all spectral windows and channels
73 Examples:
74 spw='0~2,4'; spectral windows 0,1,2,4 (all channels)
75 spw='<2'; spectral windows less than 2 (i.e. 0,1)
76 spw='0:5~61'; spw 0, channels 5 to 61
77 spw='0,10,3:3~45'; spw 0,10 all channels, spw
78 3 - chans 3 to 45.
79 spw='0~2:2~6'; spw 0,1,2 with channels 2
80 through 6 in each.
81 spw = '\*:3~64' channels 3 through 64 for all sp id's
82 spw = ' :3~64' will NOT work.
84 NOTE: mstransform does not support multiple
85 channel ranges per spectral window (';').
86 scan Scan number range
87 Subparameter of selectdata=True
88 Default: '' = all
89 antenna Select data based on antenna/baseline
90 Subparameter of selectdata=True
91 Default: '' (all)
93 If antenna string is a non-negative integer, it
94 is assumed an antenna index, otherwise, it is
95 assumed as an antenna name
97 Examples:
98 antenna='5&6'; baseline between antenna
99 index 5 and index 6.
100 antenna='VA05&VA06'; baseline between VLA
101 antenna 5 and 6.
102 antenna='5&6;7&8'; baselines with
103 indices 5-6 and 7-8
104 antenna='5'; all baselines with antenna index
105 5
106 antenna='05'; all baselines with antenna
107 number 05 (VLA old name)
108 antenna='5,6,10'; all baselines with antennas
109 5,6,10 index numbers
110 antenna='!ea03,ea12,ea17': all baselines
111 except those that include EVLA antennas
112 ea03, ea12, or ea17.
113 correlation Select data based on correlation
114 Default: '' ==> all
116 Example: correlation="XX,YY".
117 timerange Select data based on time range
118 Subparameter of selectdata=True
119 Default = '' (all)
121 Examples:
122 timerange =
123 'YYYY/MM/DD/hh:mm:ss~YYYY/MM/DD/hh:mm:ss'
124 (Note: if YYYY/MM/DD is missing date defaults
125 to first day in data set.)
126 timerange='09:14:0~09:54:0' picks 40 min on
127 first day
128 timerange= '25:00:00~27:30:00' picks 1 hr to 3
129 hr 30min on NEXT day
130 timerange='09:44:00' pick data within one
131 integration of time
132 timerange='>10:24:00' data after this time
133 intent Select observing intent
134 Default: '' (no selection by intent)
136 Example: intent='*BANDPASS*' (selects data
137 labelled with BANDPASS intent)
138 array (Sub)array number range
139 Default: '' (all)
140 uvrange Select data by baseline length.
141 Default = '' (all)
143 Examples:
144 uvrange='0~1000klambda'; uvrange from 0-1000 kilo-lambda
145 uvrange='>4klambda';uvranges greater than 4 kilo-lambda
146 uvrange='0~1000km'; uvrange in kilometers
147 observation Select by observation ID(s)
148 Subparameter of selectdata=True
149 Default: '' = all
151 Example: observation='0~2,4'
152 feed Selection based on the feed
153 NOT IMPLEMENTED YET!
154 Default: '' = all
155 datacolumn Which data column(s) to use for processing
156 (case-insensitive).
157 Default: 'all' (= whichever of the options that
158 are present)
159 Options: 'data', 'model', 'corrected',
160 'all','float_data', 'lag_data',
161 'float_data,data', 'lag_data,data'
163 Example: datacolumn='data'
