Correlated flux data for Circinus from March 2020 (blue), February 2021 (yellow), and May 2021 (red). The black points are simulated values extracted from the final images, with errors estimated using the 1σ error maps (described in Sect. 3.1.1). The total photometric flux is included in the first panel. Presented errors come from both the calibrator flux uncertainty and the statistical variation of the observables within a set of observing cycles. Near 8 and 13 μm one can see flux variations due to the edges of the atmospheric window.
