16 importasdm ---- Convert an ALMA Science Data Model observation into a CASA visibility file (MS)
19 Convert an ALMA Science Data Model observation into a CASA visibility
20 file (MS)
22 --------- parameter descriptions ---------------------------------------------
24 asdm Name of input ASDM file (directory)
25 Default: none
27 Example: asdm='ExecBlock3'
28 vis Root ms name.
29 Default: none
31 Note that a prefix (.ms) is NOT appended to this
32 name.
33 createmms Create a Multi-MS partitioned according to the given
34 separation axis.
35 Default: False
36 Options: False|True
38 For more detailed documentation on partition,
39 Multi-MS and the MPI use in CASA, please see CASA
40 Docs (https://casa.nrao.edu/casadocs/).
41 separationaxis Axis to do parallelization across
42 Default: 'auto'
43 Options: 'scan', 'spw', 'baseline', 'auto'
45 * auto: will partition per scan/spw to obtain
46 optimal load balancing with the following
47 criteria:
48 1 - Maximize the scan/spw/field distribution
49 across sub-MSs
50 2 - Generate sub-MSs with similar size
51 * 'scan' or 'spw': will partition the MS into
52 scan or spw. The individual sub-MSs may not be
53 balanced with respect to the number of rows.
54 * 'baseline': mostly useful for Single-Dish
55 data. This axis will partition the MS based on
56 the available baselines. If the user wants only
57 auto-correlations, use the
58 ocorr_mode='ao'. Note that if numsubms='auto',
59 partition will try to create as many subMSs as
60 the number of available servers in the
61 cluster. If the user wants to have one subMS
62 for each baseline, set the numsubms parameter
63 to a number higher than the number of baselines
64 to achieve this.
65 numsubms The number of sub-MSs to create in the Multi-Ms.
66 Default: 'auto'
67 Options: any integer number (example: numsubms=4)
69 The default 'auto' is to partition using the
70 number of available servers given when launching
71 CASA. If the task is unable to determine the
72 number of running servers, or the user did not
73 start CASA using mpicasa, numsubms will use 8 as
74 the default.
76 Example: Launch CASA with 5 engines, where 4
77 of them will be used to create the MMS (the
78 first engine is used as the MPIClient):
79 mpicasa -n 5 casa --nogui --log2term
80 CASA> importasdm('uid__A1', createmms=True)
81 corr_mode Correlation mode to be considered on input.
82 Default: 'all'
83 Options: ao, co, ac, or all
84 srt Spectral resolution type.
85 Default: 'all'
86 Options: fr, ca, bw, or all
87 time_sampling Specifies the time sampling (INTEGRATION and/or
88 SUBINTEGRATION) to be considered on input.
89 Default: 'all'
90 Options: i, si, or all
92 A quoted string containing a sequence of i, si,
93 or all separated by whitespaces is expected
94 ocorr_mode Output data for correlation mode AUTO_ONLY (ao) or
95 CROSS_ONLY (co) or CROSS_AND_AUTO (ca)
96 Default: 'ca'
97 Options: ao, co, ca
98 compression Produce compressed columns in the resulting measurement
99 set.
100 Default: False
101 Options: False|True
102 lazy Make the MS DATA column read the ASDM Binary data
103 directly (faster import, smaller MS).
104 Default: False
105 Options: False|True
107 Instead of writing a copy of the visibilities
108 into a standard DATA column, lazy=True will make
109 importasdm only write a lookup-table such that
110 later access to the DATA column will read the
111 ASDM binary visibility data directly. This
112 requires that the ASDM not be removed from its
113 location as long the the DATA column is
114 needed. Use method ms.asdmref() to query and
115 manipulate the reference to the ASDM.
117 lazy=True will save ca. 50% disk space and
118 accelerate the DATA column access by
119 ca. 10%. lazy=True will only work when there is
120 visibility data in the ASDM, not with pure
121 radiometer data.
122 asis Creates verbatim copies of the ASDM tables in the output
123 measurement set.
124 Default: none
126 The value given to this option must be a list of
127 table names separated by space characters; the
128 wildcard character '*' is allowed in table
129 names.
130 wvr_corrected_data Specifies which values are considerd in the ASDM binary
131 data to fill the DATA column in the MAIN table of the MS.
132 Default: no
133 Options: no|yes|both
135 * no: uncorrected data
136 * yes: corrected data
137 * both: for corrected and uncorrected data. Note
138 if both is selected, two measurement sets are
139 created, one with uncorrected data and the
140 other with corrected data (which name is
141 suffixed by '-wvr-corrected')
142 scans Processes only the scans specified in the option's value.
143 Default: none (all scans)
145 This value is a semicolon separated list of scan
146 specifications. A scan specification consists in
147 an exec bock index followed by the character ':'
148 followed by a comma separated list of scan
149 indexes or scan index ranges. A scan index is
150 relative to the exec block it belongs to. Scan
151 indexes are 1-based while exec blocks's are
152 0-based.
154 Examples:
155 '0:1'
156 '2:2~6'
157 '0:1;1:2~6,8;2:,3:24~30'
158 '1,2'
159 '3:' alone will be interpreted as 'all the
160 scans of the exec block#3'. An scan index or a
161 scan index range not preceded by an exec block
162 index will be interpreted as 'all the scans
163 with such indexes in all the exec blocks'.
164 ignore_time All the rows of the tables Feed, History, Pointing,
165 Source, SysCal, CalDevice, SysPower, and Weather are processed
166 independently of the time range of the selected exec block / scan.
167 Default: False
168 Options: False|True
169 process_syspower s processed if and only if this
170 parameter is set to true.
171 Default: True
172 Options: True|False
173 process_caldevice The CalDevice table is processed if and only if this
174 parameter is set to true.
175 Default: True
176 Options: True|False
177 process_pointing The Pointing table is processed if and only if this
178 parameter is set to true.
179 Default: True
180 Options: True|False
182 If set to False, the POINTING table is empty in
183 the resulting MS
184 process_flags Create online flags based on the Flag.xml, Antenna.xml
185 and SpectralWindow.xml files and copy them to the FLAG_CMD sub-table
186 of the MS.
187 Default: True
188 Options: True|False
190 The flags will NOT be applied unless the
191 parameter applyflags is set to True. Optionally,
192 the flags can also be saved to an external ASCII
193 file if savecmds is set to True.
194 tbuff Time padding buffer (seconds)
195 Subparameter of process_flags=True
196 Default: 0.0
198 NOTE: this time is in seconds. You should
199 currently set the value of tbuff to be 1.5x the
200 correlator integration time if greater than 1
201 second. For example, if the SDM has integrations
202 of 3 seconds, set tbuff=4.5. Likewise, set
203 tbuff=15.0 for 10-sec integrations.
204 applyflags Apply the online flags to the MS.
205 Subparameter of process_flags=True
206 Default: False
207 Options: False|True
208 savecmds Save the flag commands to an ASCII file given by the
209 parameter outfile.
210 Subparameter of process_flags=True
211 Default: False
212 Options: False|True
213 outfile Filename or list of filenames where to save the online
214 flag commands.
215 Subparameter of process_flags=True
216 Default: '' (it will save on a filename composed
217 from the MS name(s).) E.g., for vis='uid_A02.ms',
218 the outfile will be 'uid_A02_cmd.txt'.
219 flagbackup Back up flag column before applying flags.
220 Default: True
221 Options: True|False
222 verbose Produce log output as asdm2MS is being run
223 Default: False
224 Options: False|True
225 overwrite Over write an existing MS(s) or MS(s), if the option
226 wvr_corrected_data='both'
227 Default: False (do not overwrite)
228 Options: False|True
230 NOTE: the overwrite parameter affects all the
231 output of the task. If any of the following
232 exist, it will not overwrite them. MS(s),
233 .flagversions, online flag files. When set to
234 True, it will overwrite the MS, .flagversions and
235 online flag file.
236 bdfflags Set the MS FLAG column according to the ASDM _binary_
237 flags
238 Default: False
239 Options: False|True
240 with_pointing_correction Add (ASDM::Pointing::encoder -
241 ASDM::Pointing::pointingDirection) to the value to be written in
242 MS::Pointing::direction
243 Default: False
244 Options: False|True
245 convert_ephem2geo if True, convert any attached ephemerides to the GEO
246 reference frame (time-spacing not changed)
247 Default: True
248 Options: True|False
250 ALMA uses ephemerides with observer location
251 equal to the ALMA site. For later processing of
252 the radial velocity information in, e.g. cvel, a
253 geocentric ephemeris is needed. Setting this
254 option to True will perform the conversion of
255 positions and velocities on all attached
256 ephemerides in the imported MS. This will neither
257 change the time-spacing nor the duration of the
258 ephemeris. No interpolation in time is done.
259 polyephem_tabtimestep Timestep (days) for the tabulation of polynomial
260 ephemerides. A value less than or equal to 0 sets the timestep to 0.001 days.
261 Default: 0
263 Presently, VLA data can contain polynomial
264 ephemerides. ALMA data uses tabulated values.
265 Polynomial ephemerides in the SDM are always
266 tabulated using some timestep when the ephemeris
267 tables attached to the MS are written. If a non-default
268 value is used and the ASDM contains tabulated values
269 then importasdm will log a warning messages informing
270 the user that polyephem_tabtimestep is not used for
271 tabulated ephemerides.
