Expectation values of the FD131 parameters (top) and respective standard deviations (bottom) calculated over signal observations in eFF, FF, and LW camera modes. The different offsets are caused by individual mode normalisation of the parameter. The same 11-yr modulation as in the prior analysis can be seen. The gap for 2011 results from a readout error that occurred during the data retrieval from the MUST archive. One data point represents one observation.
