Notes. First column denotes which facility was used, “Arecibo” or “Goldstone” for both observatories used in monostatic mode, or “GBT” for bistatic observations between Goldstone and Green Bank. “UT Date” is the universal-time date on which the observation began, and the timespan of the received data is listed by the UT “Start” and “Stop” times. “RTT” is the round-trip light time to the target. “Baud” is the time resolution of the pseudo-random code used for imaging; baud does not apply to cw data. The baud-length is translated to delay “Resolution”, however the effective resolution might be higher if multiple samples per baud were taken. The final resolution of individual frames is listed in Table A.1. “Runs” is the number of completed transmit-receive cycles. This number does not necessarily correspond to the number of images obtained, as sometimes multiple runs were summed to increase the signal-to-noise ratio of a final image. “TE model” and “Final model” columns indicate which data sets were used in the two-ellipsoid pole search discussed in Sect. 3.2, and which in the final shape model in Sect. 3.3. The data selection is discussed in Sect. 2.2.
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.
