This is the instrument performance plot for the GIRAFFE read noise. We display
both the 'normal' read mode (used by default and in almost all OBs) and the
'Fast' read mode (monitored regularly but rarely used for science).</font><p><font size="2">

The read noise displayed here refers to a single raw frame. We display the
parameter in electrons, while the downloaded data come in ADU. </font><p><font size="2">

The label 'new CCD' refers to the current CCD in use since May 2008.
