1.3.1.0 ms.iterend

NRAO Home > CASA > CASA Toolkit Reference Manual

ms.iterend - Function

1.3.1 End the iteration and reset the selected table

Description

This sets the currently selected table (as accessed with getdata) to the table that was selected before iteration started. Use this to end the iteration prematurely. There is no need to call this if you continue iterating until iternext returns False.

See the example below.

Arguments

Returns
bool

Example

      ms.open("3C273XC1.MS")
      ms.selectinit(datadescid=0)
      ms.iterinit(["ANTENNA1","ANTENNA2","TIME"],60.0)
      ms.iterorigin()
      rec=ms.getdata(["u","v","data"])
      ms.iternext()
      ms.iterend()

    We open the MS, select an array and spectral window and then
    specify an iteration over interferometer and time, with a 60s time
    interval.  We then set the iterator to the start of the data and
    get out some data. Finally we advance the iterator to the next lot
    of data and then end the iteration.
