				BB

      BBEN is a module which performs aperture photometry on star or
 small galaxy images.  Provision is made for selected quadrants of the sky
 annulus to be weighted as zero if there is interference from nearby objects.

	...The output data file is presented below.  Because it is 132 columns
 wide, it has been broken into halves.  The date, filter, and UT information 
 are taken from the header keywords.  If they are not present, ABSENT is
 written in their place.
