SUPERNOVA/ACCELERATION PROBE ERROR BUDGET
Bryan E Laubscher
Los Alamos National Laboratory
The SuperNova/Acceleration Probe (SNAP) is a space-based astronomy experiment with the primary mission of investigating the properties of the dark energy and determining its equation of state parameters. SNAP's approach to this is to perform precise measurements of ~2,500 type Ia supernovae. These data will represent a uniform sample of high quality photometry and spectroscopy that spans the redshift range from 0.1 to 1.7. We will present the SNAP Error Budget (SEB) philosophy and framework. The SEB is a tool used to gauge the errors and error propagation in all part of the measurement process so that the overall uncertainty is understood. During design phase the SEB can identify the large error sources and facilitate their elimination. During pre- and post-launch calibration testing the SEB provides a sanity check against which the actual performance is compared. Once the as-built performance numbers are placed into the SEB, the experimental error can be calculated.
