To all the DIS spectroscopists out there, a call for opinions: When we upgrade DIS with new CCDs, how would you prefer we align the detectors with respect to the dispersion direction? If we align them so that their columns are parallel to the dispersion direction, a bad column would wipe out a strip in the spatial direction. If we align them so that their rows are parallel to the dispersion, a bad column would block one pixel worth of wavelength. Please reply to me with your preferences, so that we can try to satisfy as many users as possible!
