FOS Closeout Calibration:  Post-Costar SINGLE Aperture Flatfields
	These files are available online from
http://archive.eso.org/archive/hst_best_ref.html
or from STScI via StarView or anonymous ftp: ftp.stsci.edu/cdbs/yref.
	A detailed discussion of the advantages of re-calibration with the AIS 
method is provided in the third edition of the HST Data Handbook.  Simply 
put, all FOS observations benefit from this re-calibration.
