Performance Data Shwfs

Figure 4 shows a typical example of a SHWFS image with three CCDs reading out simultaneously. A frame rate of 400 Hz with a total of 64x192 pixels was achieved. This corresponds to an average pixel rate of 4.9 Mpixel/sec and a burst pixel rate of 7.5 Mpixel/sec. The noise level for all 12 channels is ~6 e- RMS, with a conversion factor of 1.7 e-/ADU.
