FORS 2 - CCD System

Measurement Conditions

Prescan :

[H] 16, [V] 0

Overscan :

[H] 16, [V] 0

Temperature :

- 120 °C

Bias Voltages (V) :

	Port A	Port B	Port C	Port D
VDD	24.8	24.8	24.8	24.8
RD	13.4	13.4	13.4	13.4
LG	- 4	- 4	- 4	- 4.8

The following modes have been implemented :

Mode ID	Description	Binning	Gain ( e^- / ADU )	Readout Time ( s )	Delivered for Science
1	Port A, high gain	1 x 1	1.85	97	yes
2	Port A, low gain	1 x 1	2.62	97	yes
3	Port A, high gain	2 x 2	1.85	42	yes
4	Port A, low gain	2 x 2	2.62	42	yes
5	Port A, high gain	4 x 4	1.85	19	no
6	Ports ABCD, low gain	1 x 1	( see table above )	27	yes
7	Ports ABCD, high gain	1 x 1	( see table above )	27	yes
8	Ports ABCD, low gain	2 x 2	( see table above )	13	yes
9	Port ABCD, high gain	2 x 2	( see table above )	13	yes
10	Port ABCD, high gain	4 x 4	( see table above )	7	no

Windowing through port A with high / low gain also is possible.
