Serial number	04073-17-21
First light on La Palma	May 2005
Description	E2V CCD97 Thinned midband AR coated. L3 electron multiplying CCD. Camera Picture

Operational Characteristics

Speed	Fast	Slow
Bias(ADU)	2300	2320
Gain(ADU/e)	90	8
Read Noise(e)	0.1	1
Linear to(ADU)	17500	17500
L3 Gain	410	37

Windowed readout times as follows: 
[timings made using the 'rsrun' command]

Window size	Fast	Slow
Full frame	0.7	0.7
[200:350,200:350]	100ms	100ms
[200:300,1:540]	400ms	400ms
[1:560,200:400]	400ms	400ms

Windows smaller than 150 x 150 pixels are not recommended because
of bias gradients in the first 30 rows and columns of the window

Windowing : one window only

Binning : No
