Requires:
Synopsis
Convert a CASA visibility file (MS) into an ALMA or EVLA Science Data
Model
Arguments
Inputs |
| ||
vis |
| MS name | |
| allowed: | string |
|
| Default: |
|
|
asdm |
| Name of output ASDM directory (on disk)
| |
| allowed: | string |
|
| Default: |
| |
datacolumn |
| specifies which MS data column is used to fill the
visibilites in the ASDM | |
| allowed: | string |
|
| Default: | data |
|
archiveid |
| the X0 in uid://X0/X1/X2
| |
| allowed: | string |
|
| Default: | S0 |
|
rangeid |
| the X1 in uid://X0/X1/X2
| |
| allowed: | string |
|
| Default: | X1 | |
subscanduration |
| maximum duration of a subscan in the output ASDM
| |
| allowed: | string |
|
| Default: | 24h |
|
sbduration |
| maximum duration of a scheduling block (and therefore
exec block) in the output ASDM
| |
| allowed: | string |
|
| Default: | 2700s |
|
apcorrected |
| data to be marked as having atmospheric phase
correction
| |
| allowed: | bool |
|
| Default: | False |
|
verbose |
| produce log output
| |
| allowed: | bool |
|
| Default: | True |
|
showversion |
| Report the version of ASDM class set being used
| |
| allowed: | bool |
|
| Default: | True |
|
useversion |
| Selects the version of MS2asdm to be used (’v3’)
| |
| allowed: | string |
|
| Default: | v3 |
|
bool
Example
exportasdm(vis=’ngc4826.ms’, asdm=’uid___S021_X1418_X1’,
datacolumn=’corrected’, archiveid=’S021’, rangeid=’X1418’,
verbose=False)
will produce an ASDM named ’uid___S021_X1418_X1’ using the
datacolumn ’corrected’ in the MS ’ngc4826.ms’ with minimal
log output.
The sbduration parameter controls the number of execution blocks (EBs)
into which exportasdm subdivides the visibilities from your input MS.
If the total observation time in the MS is shorter than what is given
in sbduration, a single EB will be created.
Note concerning ALMA data: exportasdm presently is not able to export
from MSs containing WVR data. If you attempt to export such an MS, you
will receive an error message saying that you can only export data of
processor type "CORRELATOR". It will also give you the list of SPWs
which contain CORRELATOR data. You will then have to split out these
SPWs using the task "split" and run exportasdm on the resulting MS.
Also EVLA data can be exported. Note here that exportasdm does not produce
online flags and that a subsequent reimport of the data must be done with
online=False. Also, importevla will only work on your ASDM if you have
exported it with apcorrected=False (the default).
importevla(’xosrosdm’, vis = ’xosro.ms’)
exportasdm(vis=’xosro.ms’, asdm=’xosrosdm’, apcorrected=False)
importevla(asdm=’xosro2asdm’, vis=’xosro2-reimp.ms’, online=False)
