... Required coalignment to mirrors ~100µm Coalignment and pencil beam Accurate positioning of the X-ray baffle with respect to the centre of the mirror system was achieved by taking as reference the location of the centre of the mirror system - defined by two reference points on the Mirror Module structure and the location of the centre of the X-ray baffle defined by two reference points on the X-ray baffle structure and then performing the corresponding alignment of those reference points. ...

... The primary channel receives the desired astronomical signal corrupted by RFI (radio frequency interference ) coming in the sidelobes of the main beam. ... If the interference-to-noise in the reference and primary channels are equal ([pic]), the noise in the system output (at the frequencies where the interference signal was located) will be almost twice as high as in the primary input before filtering. ... The signal path through the adaptive filter illustrates the iterative nature of this system. ...
