Changes to Uv Ir PSF

08 Nov 2013

• Added analysis section with estimates of ACIS optical and IR brightness limits.

30 Nov 2017

• Revised estimates based on 2014/2015 observations of Betelgeuse and Vega
• Raw fluxes are much smaller; instead of assuming Vega has magnitude 0 and scaling by the Betelgeuse/Vega flux ratios, the planning limits are based on the magnitudes provided by simbad.

• reorganized text to merge the relevant analyses into a single section
