Figure 4
LSF measurement on a lens-coupled CCD detector. (a) Dark-subtracted image of a thin slit, tilt angle 3.4° with respect to pixel direction XX′, image levels on logarithmic scale. (b) Single cross section along XX′ providing the pre-sampling LSF FWHM. (c) Summed cross sections along YY′ (orthogonal to the slit) showing the LSF tails down to less than 10−3 relative intensity levels.
