This is the FULL Health Check plot for monitoring the 
resolution of  the GIRAFFE
arclamp calibration data. We display here the resolving power R =
&lambda;<sub>0</sub>/&Delta;&lambda;. &Delta;&lambda; is the QC1 
parameter mean_resol
which is the mean of all accepted emission line widths. The reference values
for the GIRAFFE resolution are indicated as red broken lines (taken from the
User Manual).</font><p><font size="2">

Corresponding data from the GIRAFFE master calibration (re)processing project are available for the Medusa plots and marked separately.
Note that these indicate that the corresponding data calculated between
2006-07-01 and 2008-01-01 have a systematic offset that is not real, due to
some pipeline bug.

This plot monitors the 
HC data taken in high resolution (H525.8B) and low resolution (L543.1, Medusa1
and 2 only).</font><p><font size="2">

</font><p><font size="2"> Up to 2008-01, these numbers were approximate. With 
pipeline version giraf-2.5 and higher (after that date) accurate numbers were provided. Only these ones should be taken
for reference.
