Example of a 3.5 h RFI mask for A1 (top) and A2 (bottom) for a simultaneous observation using rfifind with -time 1 and default parameters; colored sections are masked out. The mask criteria acts differently in each antenna given their different sensibility, so the plots are not in the same scale. RFIs affect only 1.3% of this observation for A1 and less than 6.3% for A2. We note that the persistent RFIs in A2 are monochromatic and affect individual channels only (2 of 64 in this case). The frequency channels on the borders of the bandwidth in A2 are removed due to the design of the receiver.
