Notes. CC is the two-letter country code. Site latitude, longitude (format dms) and elevation (AMSL in m) are given in the WGS84 datum. Telescope: Tx is the telescope aperture in cm. Method is the recording method: IMG means digital (CDD, CMOS) sequential imaging, VID is analog video recording. TimeSrc is the used timing source and method: GPS (Global Positioning System) means 1-PPS (one pulse per second) driven video-time-insertion (VID) or camera-internal GPS timestamps (IMG). NTP denotes a Network Time Protocol computer system clock synchronization. Observation: either positive (occultation detected/recorded) or negative. ExpTime is the exposure time in seconds, DeadTime is the dead time in seconds between two subsequent images during the recording.
