16 sdatmcor ---- Offline correction of residual atmospheric features
20 The task sdatmcor provides the capability of offline correction of
21 residual atmospheric features in the calibrated single-dish spectra
22 which result from the difference of elevation angle between ON_SOURCE
23 and OFF_SOURCE measurements.
25 The correction factor is derived from the atmosphere model based on
26 the atmospheric properties (temperature, pressure, etc.) measured
27 during the observation. The model is constructed by the atmosphere
28 (at) tool.
30 For spw selection, two selection parameters, spw and outputspw,
31 are available. The former specifies the data to be
32 corrected while the latter corresponds to the spw for output.
33 In practice, intersection of spw and outputspw is corrected.
34 For example, when spw='19,23' and outputspw='19', spw 23 is not
35 corrected because data for spw 23 is not written to outfile so
36 that the correction is not meaningful.
37 For data selection parameters other than spw, only data selected
38 by data selection parameters are corrected and written to the outfile.
40 Note that outfile will have the data column DATA regardless of
41 what data column exists in infile.
43 --------- parameter descriptions ---------------------------------------------
45 infile name of input MS.
46 datacolumn name of data column to be used ["data", "float_data", or "corrected"]
47 outfile name of output MS.
48 overwrite allow to overwrite the output file if already exists.
49 field Select fields. Use field id(s) or name(s).
51 If field string is a non-negative integer, it is assumed to

81 considered an antenna name.
83 If specified selection doesn't contain any autocorrelation,
84 the selection will be tweaked to include autocorrelation data.
85 For example, 'PM02' will be interpreted as 'PM02&&&'.
87 Default: '' (all)
88 Example:
89 antenna='5&6'; baseline between antenna index 5 and
90 index 6.

107 day in data set

146 Note that outputspw specifies the list of spw ids to output.
147 Spw ids to be corrected should be specified by spw.
149 Note also that channel selection is not available for this task.
150 gainfactor Gain factor to multiply correction term.
152 In ALMA data reduction, intensity of calibrated spectra, antenna
153 temperature Ta* in unit of Kelvin, is converted to Jansky (Jy)
154 by multiplying conversion factor. This parameter is intended to
155 apply exactly the same multiplicative factor to correction term.
156 If no conversion is applied to spectral data, gainfactor should
157 be 1.0, which means that the correction is in unit of Ta*.
158 The value can be float, dict, or string. Default is 1.0.
160 Float value is interpreted as fixed factor, which is applied to all spws.
162 Dict should be the pair of spw id (key) and the factor to be applied (value).
163 Key should be string rather than int.
165 If string is given, it should be the name of caltable. For caltable,
166 inverse square of stored value is applied.
168 Default: 1.0
