Example of the 1.5 keV TM1 PSF at an off-axis angle of 30’ in the original resolution (left) and the reconstructed resolution (right), where each original pixel is sub-divided into 10 × 10 sub-pixels. The histograms at the bottom show the flux distribution in the brightest pixel row (left) and in the ten corresponding sub-pixel rows (right). The modified bicubic resampling method enhances fine structures. The white circle indicates the minimum HEW.
