1 Visible Flexure Camera Analysis J. Kent Wallace March 14, 2006

2 Flexure Movie (view in presentation in ‘Slide Show’ mode)

3 Analysis There exist a 2x2 matrix, M, that transforms the measured flexure camera coordinates, F m, to PHARO coordinates, P m : This can be inverted: The error in the fit for the data is:

4 Flexure Data Fit

5 Summary Error in estimating P from F is ~0.15 pixel (rms) or ~3.75 mas. –PHARO camera and flexure camera not well sync’ed to each other. Data sampling could be off by as much as 10 seconds. Likely error is smaller by some amount. Next step is to try and close the loop on the flexure camera.
