The plots are arranged per fibre system. Within each fibre system, all settings are displayed. Their num_fib parameter should be almost the same (see below). Hence both the regular Health Check calibration, and the science-driven daytime calibrations are included here.
The IFU settings show some small variation around 315 since some of the last fibres may be truncated, depending on the setting. Most likely, problems will show up only per fibre bundle (sets of 20 fibres).
A detailed record of the performance of each fibre, and a record of the available/missing fibres, is available here.
