In light of the new operational model implemented in October, 2011 (QC-XXLight), SINFONI science data is no longer processed.

A SINFONI obsnod science frame (this data has a PRO.CATG = OBJECT_NODDING_STACKED and has the pipeline product naming convention prefix SI_SBNS).

The median collapse of an obsnod science cube (this data has a PRO.CATG = MED_COADD_OBJ and has the pipeline product naming convention prefix SI_SMCD).

QC1 plots

The QC1 plots for the SINFONI SCIENCE trending are divided into 3 html pages. The QC1 SCIENCE trending pages monitor the following:

• a test for an over-flux condition (>= 10,000 ADU) and, if detected, the number of affected pixels.
• the difference in date and airmass between the science observation and its associated telluric STD star.
• the difference in detector and grating temperature between the science observation and its associated wavelength calibration.

QC Reports for SCIENCE Frames

QC Report 1                                                                                            QC Report 2

QC Report 1:
UL: the OBJECT_NODDING_STACKED full detector intermediate science image with the number of saturated pixels listed.
UR: the MED_COADD_OBJ median cube collapsed science image. A number of paramters are listed: the Program ID, the Obs ID, the target name, and for the brightest source detected:
source center (pixels), the integrated flux (within 3 sigma), the isophotal area (3 sigma), the net flux per pixel, the image FWHM (arcsec), the DIMM seeing corrected for the same airmass and filter used by this standard star, the status of the AO loop (OPEN or CLOSED), the position angle of the brightest source (degrees CCW from the x-axis), and its elongation and ellipticity.
The source center, its position angle, and its FWHM are marked on the image. 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:

pixel_scale is given by the keyword INS.OPTI1.NAME.
LL: the (scaled) difference between two cube planes. Plane 100 - Plane 2072. The wavelengths of these planes are listed to the right of this image.
LR: a horizontal (blue line) and vertical (red line) cut through the center of the brightest detected source of the MED_COADD_OBJ median cube collapsed science image. The respective averages through this center are shown as dotted lines.

QC Report 2:
UL: three single column traces of the current product (OBJECT_NODDING_STACKED) through: x = 500 (dark grey), x = 1000 (middle grey), x = 1500 (light grey) and an averaged sum of all columns (blue).
UR: three single row traces of the current product (OBJECT_NODDING_STACKED) through: x = 500 (dark grey), x = 1000 (middle grey), x = 1500 (light grey) and an averaged sum of all rows (blue).
LL: the background-subtracted spectrum of the brightest science source. This spectrum is computed by the post-pipeline script QCsinfo_sci.py. The green line is the peak flux extracted from each cube plane at the position of the brightest source, whereas the blue line is the average flux over the FWHM measured for the brightest source. The red line is an estimate of the flux rms.
LR: a logarithmic histogram of the OBJECT_NODDING_STACKED full detector image is shown as a dark blue line, while the reflection of the non-positive flux histogram is shown in light blue.

QC Report 3 (only created if an over-flux is detected!)

QC Report 3
TOP: a logarithmic histogram of the OBJECT_NODDING_STACKED full detector science image with the persistence critical region shown as a red dotted line.
LL: the OBJECT_NODDING_STACKED full detector intermediate product image.
LR: an estimate of the location of possible persistence critical pixels.

Trending and Issues

The detection of persistence from a previous science target, STD, or PSF star in the image of the current science frame is a reason for downgrading the science OB. The telluric standard star should be within 1 day and 1 airmass of the science exposure. Finally, temperature differences of 2 ^oC or less are tolerated between the science exposure and its wavelength calibration.

History

Trending and scoring of SINFONI science data began 2009-06-15.
