The read noise is 6.0 electrons and the gain is 1.74 electrons/ADU. The scale is 0.219 arcseconds/pix. The detector can be operated in binned mode, such as 2x2 pixels. The CCD is known to have a peak quantum efficiency near 95% in the R band, and has shown itself to be readily calibrated, and free from gross cosmetic defects. The set of BVRI filters for this CCD are the Kron-Cousins photometric system. The filters have the following central wavelengths and widths: Center FWHM Width/delta Wavelength lambda Filter (Angstrom) (Angstrom) ------ ---------- ------------ B 3480 1077 V 5450 836 R 6460 1245 I 8260 1845
