TMAS Performance Budget and Analyses

Benefit of fast frame capture to reduce residual P3K tip-tilt error (for various observing wavelengths 0.4 - 2.2 microns)

Assumptions:
  • Kolmogorov turbulence w/ infinite outer scale
Note:
  • Conversion from RMS mas to equivalent RMS WFE for error budget is ~ 6 nm RMS / mas RMS residual TT
