[Artist's Concept of AXAF-I] AXAF Project Science: Cu-K spot sizes

------------------------------------------------------------------

Here are the images of Cu-K spot from the EIPS at XRCF. The overlay grid has a spacing of 500 microns (0.5 mm). The GIF images are only for part of the total FITS image. For the higher voltages there is some punch-through which shows up as enhanced background in a circle centered on the pinhole image. (The GIF images are entirely inside this circle.)

Integration time  = 300 sec
Filter            = 50 microns Cu
Magnification     = 3.59
Data taken        = 1996-05-29

VHRIFIT           = 1998-02-26
GAPFIL            = sumb.gap
VLEXTRCT          = 1998-02-26
