  • Outliers in the gradient (dF/dx) are only meaningful when the RMS(dF/dy) is small, otherwise the deviation of dF/dx is due to a larger scatter in the measurement (e.g. non-photometric conditions, or high sky-variations). The same holds for dF/dy; here the RMS(dF/dx) should be low.

This plot

This is the trending plot for the ISAAC QC parameters derived from photometric zeropoint frames. These plots describe:
1. The spatial gradient of the photometric zeropoint along the x-axis.
2. The spatial gradient of the photometric zeropoint along the y-axis.
3. The RMS of the gradient in x derived from the linear regression analysis
4. The RMS of the gradient in y derived from the linear regression analysis

The FOV gradients are derived from the five single raw frame exposures. Since the five measurements are acquired at five different positions on the detector, a simple spatial photometry can be derived for reasons of health check. These measurements serve as a quick look.

This QC check is complementory to the annualy acquired illumination checks. The illumination checks puts the star on a finer grid on the detetctor and fits a non-linear 2-dim polynomial. Find more information about ISAAC ZPOINT calibrations here.

Other QC parameters related to detector properties (like photometric zeropoints, linearity) are trended.  

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
