This is the trending plot for the GIRAFFE QC parameters derived from BIAS frames, fast readout mode. This mode is operational since the begin of P86 (October 2010). It is used for Argus observations.

These plots describe:
1. the BIAS level in masterbias frames,
2. the read noise (RON) of a single raw frame,
3. the read noise (RON) of a master frame,
4. the collapsed structure of a masterbias in X direction,
5. the collapsed structure in Y direction,
6. the number of bad pixels.

There is sometimes pick noise visible in this readout mode.
