Lennon VATT Spectrograph

  • STA0520A CCD
  • 2688×512 pixels, 15 microns
  • ITL Serial Number 8228
  • Detector operating temperature -110C
  • Gain = 1.3 e/DN with setting 10
  • Gain = 2.6 e/DN with setting 5
  • For both gains the full well is ADC limited (65k DN), so this is 85,000 or 170,000 electrons.
  • Noise is 3.4 electrons (3.2 in overscan region)
