[Last Change: 19 Apr 2019 (rev 3)]
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.
19 Apr 2019
- reorganized text to merge the relevant analyses into a single section
