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.
The QC parameter is monitored for the left beam
and for the four broad band filters in the common filter wheel: B_Y, B_H, B_J and B_K,
separately. The dual beam filter wheel is 'CLEAR' in classical imaging mode.
