Trending plot for number of not successfully found, traced, and
wavelength-calibrated fibres in IFU calibrations. 
The LR grisms have four pseudo slits; wave_lost is determined separately for
each but scored only for pseudo slit 2. Only measurements executed with
IFU shutter OFF are plotted. MR and HR grisms use
pseudo slit 2 only.  
Historical trending plots show only the number of fibres that could not be
successfully identified from IFU flat-field calibrations (QC parameter
num_lost). Beginning with
October 2009, trending also includes those fibres that could not be
wavelength calibrated (QC parameter wave_lost).

       General information
 
 Click on any of the plots to see a close-up version. The latest date is indicated on top of the plot. If configured, 
data points belonging to the latest date are specially marked
statistical averages are indicated by a solid line, and thresholds by broken lines
outliers are marked by a red asterisk. They are defined as data points outside the
threshold lines
"aliens" (= data points outside the plot Y limits) are marked by a red arrow (↑ or ↓)
