We also reviewed in some detail plans for the permanent fiber-optic calibration system. The light sources will be housed in a special room behind the telescope bays. Light from the screen goes through the full optical chain. Fibers terminate on either side of each camera. Light gets to the pixels after reflecting at the mirror.
Fibers terminate at the center of each mirror, and diffused light illuminates the pixels directly.
Plans for atmospheric monitoring were summarized following the baseline presented at Malargue by Roger Clay. There was discussion of the phase function measurement, but I do not think there are any new developments to report in regard to atmospheric monitoring. Auger participants at the meeting were Jeff Brack, Jim Matthews, Rishi Meyhanden, Matthias Kleifges, John A.J. Matthews, Byron Dieterle, Mike Roberts, Brian Fick, and Paul Sommers. We also benefited during part of the meeting from HiRes guests Stan Thomas, Lawrence Wiencke, and John N. Matthews.
