STA0500A CCD
4064×4064 pixels, 15 microns
Gain = 1.9 e/DN
The full well is ADC limited (65k DN), so this is ~120,000 electrons.
Noise is ~3.9 electrons
Sensor is ITL sn8301

• A replacement STA0500A back illuminated 4K CCD, ITL serial number 8301, was installed March 2017, and updated 26 January 2018. It is similar to the September 2007 one, including its QE.
• pixel scale: 0.188 arcsec/pixel
• wavelength range: 300 - 1000 nm, peak 96% at 450 nm
• Preamplifiers added October 2008 inside the dewar. These give faster readout and lower noise.
