SNR calculations
  • Are captured in spreadsheet megyeri:\\My Documents\COO\Projects\TMAS\Systems Engineering\SNR calculator.xls
    • 1 hr Neo integration captured at 30Hz; 1 e- read noise; 20% spectral bandwidth; r' band; 10% Strehl ratio; 25% total efficiency (incl. qe)
      • Implies SNR = 10 on AB = 23.7 (4700 source cnts / sqrt(108,000) noise cnts)
