This plot
Measurements of the image quality from imaging standard star observations.
Values are currently determined as FWHM in X and Y direction.
Pipeline values are in pixels which have been converted to arcsecs using the
pixel field-of-view of 0.0453 arcsec/px.
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 ↓)
- you can download the data for each parameter set if the 'Data downloads' link shows up
