Model Procedures (Instrument, Maksutov Baseline) • Basic Assumptions • Wide FOV Maksutov Optics with 9.6 m2 Optical Aperture (Lamb, Pitalo; internal OWL notes) • BG-1 UV filter • Bi-alkali photocathode (Philips PMT Data Handbook) • Light spot size assumed Gaussian with RMS diameter 0.6 - 2.1 mm (f(qView)) • Pixel size of 0.08o (2.9 mm diameter) assumed • Relative shower position (in angular pixel of 0.08o) mapped appropriately into relative focal plane pixel • PE signal calculated from 3 x 3 pixels centered on signal pixel. Gaussian spot is integrated for each pixel assuming a 95% live area and Poisson fluctuated. • Trigger formed by summing 3 x 3 pixel response
