– With M. Horning, designed, built and commissioned in Dec 2008 a
hybrid LED/incandescent flat-field source for the Vatican Advanced Technology

– I provide technical feedback and detector characterization for both
the old 2048×2048-pixel CCD camera of the VATT (since it first
displayed non-linear response behavior) and its new 4096×4096-pixel
replacement (which until Nov 2008 had been plagued by another kind of
non-linearity;
– I wrote an IRAF task (display4k) to bias-subtract, scale and
merge the two halves of the VATT CCD read through different amplifiers into
a single flat FITS image and display it;
– I wrote an IRAF/ICE control script (standards) for the VATT to automatically cycle through multiple
exposures and/or filters.
