Convert an ALMA Science Data Model observation into a CASA visibility file (MS) or single-dish data format (Scantable).
The conversion of the ALMA SDM archive format into a measurement set. This version
is under development and is geared to handling many spectral windows of different
shapes.
................
Keyword arguments:
asdm -- Name of input ASDM file (directory)
default: none; example: asdm='ExecBlock3'
.... vis -- Root ms or scantable name, note a prefix (.ms or .asap) is NOT appended to this name
default: none
.... singledish -- Set True to write data as single-dish format (Scantable)
default: False
>>> singledish expandable parameter
antenna -- antenna name or id.
.... corr_mode -- correlation mode to be considered on input. Could
.... be one or more of the following, ao, co, ac, or all
.... default: all
.... srt -- spectral resolution type. Could be one or more of
.... the following, fr, ca, bw, or all
.... default: all
.... time_sampling -- specifies the time sampling, INTEGRATION and/or
SUBINTEGRATION. could be one or more of the following
i, si, or all.
........ default: all
.... ocorr_mode -- output data for correlation mode AUTO_ONLY
(ao) or CROSS_ONLY (co) or CROSS_AND_AUTO (ca)
........ default: ca
........
.... compression -- produces comrpressed columns in the resulting measurement set.
default: False
.... asis -- creates verbatim copies of the ASDM tables in
.... the output measurement set. The value given to
........ this option must be a list of table names separated
........ by space characters; the wildcard character '*' is
allowed in table names.
.... wvr_corrected_data -- specifies wich values are considered in the
ASDM binary data to fill the DATA column in
the MAIN table of the MS. Expected values for
this option are 'no' for the uncorrected data
(this is the default), 'yes' for the corrected
data and 'both' for corrected and uncorrected
data. In the latter case, two measurement sets
are created, one containing the uncorrected
data and the other one, whose name is suffixed
by '-wvr-corrected', containing the corrected
data.
.... scans --.... processes only the scans specified in the option's value. This value is a semicolon
.... separated list of scan specifications. A scan specification consists in an exec bock index
followed by the character ':' followed by a comma separated list of scan indexes or scan
index ranges. A scan index is relative to the exec block it belongs to. Scan indexes are
1-based while exec blocks's are 0-based. "0:1" or "2:2~6" or "0:1,1:2~6,8;2:,3:24~30" "1,2"
are valid values for the option. "3:" alone will be interpreted as 'all the scans of the
exec block#3'. An scan index or a scan index range not preceded by an exec block index will
be interpreted as 'all the scans with such indexes in all the exec blocks'. By default
all the scans are considered.
.... ignore_time -- All the rows of the tables Feed, History, Pointing, Source, SysCal, CalDevice, SysPower,
and Weather are processed independently of the time range of the selected exec block / scan.
.... process_syspower -- The SysPower table is processed if and only if this parameter is set to True.
.... default: True
.... process_caldevice -- The CalDevice table is processed if and only if this parameter is set to True.
.... default: True
.... process_pointing -- The Pointing table is processed if and only if this parameter is set to True.
.... default: True
.... process_flags -- Process the online flggs and save them to the FLAG_CMD sub-table.
.... default: True
>>> process_flags expandable parameter
tbuff -- Time padding buffer (in seconds).
default: 0.0
.... applyflags -- Apply the online flags to the MS.
.... default: False
savecmds -- Save the online flags to an ASCII file.
default: False
outfile -- Filename to save the online flags.
default: ''
.... verbose -- produce log output as asdm2MS is being run.
.... overwrite -- Over write an existing MS.
.... showversion -- report the version of the asdm2MS being used.
.... useversion -- Selects the version of asdm2MS to be used (presently only \'v3\' is available).
default: v3
1.8.0
