This plot
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).
Template ID: ifu_cal_DayCalib (daytime Health Checks), ifu_cal_NightCalib
(attached night-time). Pipeline recipe: vmifucalib.

Click on any of the plots to see a close-up version.
The latest date is indicated on top of the plot, data points belonging to that date are specially marked.
If configured,
- 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 ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
