These are the trending plots for the SINFONI QC parameters defined for the image quality as measured for the telluric standard stars
(H+K-band / all pixel scales).

Plot #1 is a one-to-one comparison of the image quality achieved by SINFONI and the seeing as measured by the DIMM site-monitor. The DIMM seeing has been adjusted to the wavelength and airmass of the standard star observation. The image quality (IQ) plot shows the FWHM of the STD star and the corrected DIMM plotted against one another. CLOSED loop (AO) observations are plotted as solid circles, while OPEN loop (non-AO) observations are shown as open circles.

Plot #2 shows Delta_IQ = sinfoni telluric standard star FWHM - DIMM seeing for all observations with SINFONI in CLOSED loop mode.
This parameter is scored.

Plot #3 shows Delta_IQ = sinfoni telluric standard star FWHM - DIMM seeing for all observations with SINFONI in OPEN loop mode.
This parameter is scored.

NOTE: The conversion from pixels to arcsec for the image FWHM takes into account the fact that the reconstructed SINFONI cube has rectangular pixels. The reconstructed pixels are such that on-sky Delta_X = 0.5*Delta_Y.
The correct conversion, in terms of the source position angle (PA), is given by:
the pixel_scale is given by the keyword INS.OPTI1.NAME.
