P., B. A. Babcock, J. M. Pasachoff, A. A. S. Gulbis, J. L. Elliot, M. J. Person, and J. W. Gangestad. POETS: Portable Occultation, Eclipse, and Transit System. PASP, 118, 1550-1557, 2006. POETS: Portable Occultation, Eclipse, and Transit System Imager POETS is optimized for occultation and related observations. The core of this system is the Andor Technology DV-887 (now DU-897) frame-transfer camera, featuring a high frame rate, minimal dead time, high quantum efficiency, and low read noise. The POETS works with a compact GPS timing system with microsecond accuracy, and a high-performance computer system capable of sustained fast frame rates. The camera has 16 micron square pixels in a 512 x 512 format. Its read noise and full-frame readout rate range from 6 electrons/pixel and 3 Hz in conventional mode to less than 1 electrons/pixel and greater than 30 Hz in electron-multiplying (EM) mode.
