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)
