| Convert an ALMA Science Data Model observation into a CASA visibility file
| |
| Convert a Science Data Model (SDM) dataset into a CASA Measurement Set (MS)
| |
| This version is under development and is geared to handling EVLA specific flag and
| |
| system files, and is otherwise identical to importasdm.
| |
| | |
| Keyword arguments:
| |
| asdm -- Name of input SDM 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
| |
| SUBINTEGRAION. 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.
| |
| | |
| | |
| verbose -- produce log output as asdm2MS is being run
| |
| | |
| showversion -- report the version of the asdm2MS being used.
| |
| | |
| EVLA-specific parameters:
| |
| -------------------------
| |
| | |
| applyflags -- apply the online flags from the SDM Flag.xml table to the MS
| |
| | |
| >>> applyflags expandable parameter
| |
| tbuff -- (float) time padding buffer (seconds, default=1.0)
| |
| | |
| Examples:
| |
| | |
| importevla(asdm='CLowTest_000',ocorr_mode='co')
| |
| | |
| Produces MS CLowTest_000.ms w/o autocorrelations.
| |
| You will find the Antenna.xml and Flag.xml in the
| |
| MS directory (e.g. for later use).
| |
| | |
| importevla(asdm='CLowTest_000',applyflags=True)
| |
| | |
| Produces MS CLowTest_000.ms including the
| |
| Antenna.xml and Flag.xml tables. Will also flag
| |
| the data using the on-line flags in the Flag.xml
| |
| table.
| |
| | |
| importevla(asdm='CLowTest_000',applyflags=True,tbuff=2.0)
| |
| | |
| As above, but uses a more conservative 2sec buffer
| |
| before the start and after the end timeranges.
