Abstract:
The effect of short term focus changes on Hubble Space Telescope images
after the refurbishment mission is examined. Based on simulations we
conclude that image quality will not be degraded significantly for the
cameras if focus variations are within 
microns in the blue and
within 
microns in the UV. The tolerance for the spectrographs is
wider, about 
microns.
