NOTCam S/N Estimates for Point-Source Observations ================================================== This a is Table of S/N vs Time vs Filter for NOTCam in 0.23"/pixel and 0.08"/pixel imaging modes. Assumed are: the readout noise~10e-/pixel, the dark current ~1e-/sec. Sky/background counts used in the calculation of the estimates were taken from ARNICA data taken in Aug97 when ARNICA was used on NOT. Results are for point-sources with photometry performed using a 1" aperture with 0.6" FHWM seeing conditions. Tables show Time (horizontal axis) vs S/N that will be achieved (vertical axis). Values are in magnitudes. NOTCam 0.23"/pixel mode. ------------------------ New OCLI J filter Time (sec) 1 10 30 60 300 900 1800 3600 S/N 3 18.8 20.1 20.7 21.1 22.0 22.6 23.0 23.4 10 17.5 18.8 19.4 19.8 20.8 21.4 21.8 22.2 20 16.8 18.1 18.7 19.1 20.0 20.6 21.0 21.4 50 15.8 17.1 17.7 18.1 19.0 19.6 20.0 20.4 100 15.1 16.4 17.0 17.4 18.3 18.9 19.3 19.7 New OCLI H filter Time (sec) 1 10 30 60 300 900 1800 3600 S/N 3 17.8 19.1 19.7 20.1 21.0 21.6 22.0 22.4 10 16.5 17.8 18.4 18.8 19.7 20.3 20.7 21.1 20 15.7 17.0 17.6 18.0 18.9 19.5 19.9 20.3 50 14.7 16.0 16.6 17.0 17.9 18.5 18.9 19.3 100 14.0 15.3 15.9 16.3 17.2 17.8 18.2 18.6 New OCLI K' filter (short K with shorter thermal cut-off than standard K).
