AXAF Project Science: Cr-K spot sizes
Here are the images of Cr-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 = 44 microns V Magnification = 3.59 Data taken = 1996-05-30 VHRIFIT = 1998-02-26 GAPFIL = sumb.gap VLEXTRCT = 1998-02-26
