Gain* 16 bits @ 200 kHz, -25°C

Gain State 1 18.9 e-/ADU

Gain State 4 3.9 e-/ADU

Gain State 8 1.9 e-/ADU

Gain State 16 0.9 e-/ADU

Gain State 4*** 3.7 e-/ADU

Read Out Noise* 16 bits @ 200 kHz, -25°C

Gain State 1 47.4 e-Noise

Gain State 4 11.4 e-Noise

Gain State 8 10.1 e-Noise

Gain State 16 9.9 e-Noise

Gain State 4*** 16-17 e-Noise (unknown temperature)

Note: CCD must be binned at least 2:2 to reach the maximum ADU level in Gain State 1. Single pixel full well is obtained in Gain State 4.

Full well capacity (@ Gain State 4) = 250.9 Ke-.

CTE (could be temperature dependent if the CCD is bad)

No data, but at -25°C it will be close to perfect

Dark current* (temperature dependent)

12.3 e-/second @ -25°C

Linearity* (could be temperature dependent if the CCD is bad)

0.33% Nonlinearity, shouldn’t change with gains

Readout Time** @ 1x gain

14 bits @ 200 kHz 5.4 seconds

16 bits @ 40 kHz 26.6 seconds

16 bits @ 200 kHz 5.4 seconds

These are general readings from the data sheet. More precise numbers would have to be generated by looking at the signal with an oscilloscope at the different gain settings.

***16 bits @ 200 kHz 5.4 – 7.5 second range

Bias flats

TBA

Hot pixels, bad columns, traps

TBA

hot pixels - darks

bad columns - darks and bias

traps – may be on low level dark or bias

Flat fields using solar spot (?)

QE curves**

See data sheet, unknown coating probably VIS-AR

Image quality/PSF

TBA

best 2 pixels FWHM

A/D histogram

TBA

Flat field

Noise characteristics – darks? look for patterns

Cosmic ray characterization

What is wanted here?

1/cmÙ2/sec @ sea level, higher at Keck

Temperature regulation accuracy

How accurate does it need to be?

Depends on how stable you need to keep the dark current and the appearance of hot columns
