Site latitude, longitude (format dms) and elevation (AMSL in m) are given in the WGS84 datum. Telescope: Tx refers to the telescope aperture in cm. Method is the recording method: IMG means digital (CCD, CMOS) sequential imaging, while VID means analog video recording. TimeSrc refers to the used timing source and method: GPS: 1-PPS (one pulse per second) driven video-time-insertion (VID) or camera-internal GPS timestamps (IMG). NTP: Network Time Protocol computer system clock synchronization. CamGPS: Camera synchronized directly to a GPS signal for timestamping accuracy. ComGPS: Computer synchronized to a GPS signal. ComNTP: Computer synchronized using the Network Time Protocol. TimeBox: A TimeBox is used for precise timestamping during observations. IOTA-VTI: A hardware device developed by IOTA (International Occultation Timing Association) for video time insertion. Other: Any other synchronization method not listed above. Observation can be either positive (occultation detected/recorded) or negative (occultation not detected). ExpTime represents the exposure time in seconds, while DeadTime refers to the interval between subsequent images in seconds. The sampling cadence is the sum of ExpTime and DeadTime.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
