We are in the process of commissioning a new generation of quality control software, designed as modules (``libraries'') that can be seamlessly integrated with other pieces of software, allowing also for automation and inclusion in the normal post-processing flow.
This has been completed for ALFOSC; see for a graphical representation of the results:

The software for the remaining instruments will be upgrade over the next few months.
