SPHERE news:
Note that the current Health Check monitor runs with an incomplete pipeline and an incomplete set of QC1 parameters.
QCG can currently not guarantee completeness and significance at the usual level.
This plot shows the fractional fixed pattern noise derived from the
normalized master flat. In dual beam imaging mode the QC parameter is
monitored for the left and the right beam and for the four two dual beam
filters D_H23 and D_K12 separately.
