Example of results obtained with bogopix on the simulated data set used in Tristram et al. (2011), where constant gains biases were applied. The colours distinguish four different bolometers. Dots correspond to individual measurements, and the thick line is a smoothed representation of these results with a 50 ring width. We plot relative reconstructed gains, with respect to their unbiased value. In this simulation, each bolometer’s data was biased by factors of respectively 1.98 (blue), 0.77 (green), 0.50 (black) and 0.07% (orange) respectively which is precisely reflected by the recovered bogopix value.
