shadow
       
	Task to detect baselines with shadowed antennas.  The
	amplitude of the corresponding visibilities is incremented by
	one.  This, when converted to FITS via gl2fit, will get
	flagged.

 in (default=STDIN)

	Name of the input LTA file.


 out (default=STDOUT)

	Name of the output LTA file.


 obj (default="." ==> All sources)

	Regular expression to match the selected source names.


 poln (default=-1 ==> 130 MHz channel)

	The polarization channel to use.  This is used only to detect
	the shadowed antennas.  However, visibility in both polarization
	channels is flagged.
