Measured image quality versus expected image quality from science observations.
Measured image quality: median FWHM of cross-dispersion profile in combined frames.
Expected image quality: DIMM seeing corrected for telescope diameter, airmass, and wavelength.
Downloaded data for measured IQ come in pixels, correction is 0.086
arcsec/pix.
General information
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
