Mauna Kea Filters Installed in NSFCam




The NSFCam and the SpeX slit viewer are currently using the Mauna Kea Near-Infrared filter set. JPEG plots and ascii files containing the transmission profiles of these new filters are available here:

Also available are the preliminary results on the characterization of the new filters (i.e., calibration and color terms with respect to the older filters).
