8. Field of View (FOV) Each channel shall have an array of 16 pixels each with a FOV : 20x AF/16(horizontal x elevation) where AF is 3.2. The combined FOV: 20x 3.2 (horizontal x elevation). NCKU UCB Tohoku Array Photometer Mechanical H. Fukunishi

9. PMT Vibration Test Tube installed in AP Qualification Test Unit Date: 18/19 Dec., 2000 Location: . ISAS (Institute of Space and Astronautical Science) Max Level: Sin 25G (perp. to mounting plane), 0.5G (other axes) Random 0dB (perp. to mounting plane), -12dB (other axes) . No resonance signature up to 150 Hz. The PMT survived all the trial and output signalsseems normal. NCKU UCB Tohoku Array Photometer Mechanical H. Fukunishi
