Right ascension: 171.4737996346090° Declination: 26.1722162779325° No. sessions: 284 No. delays: 12361 Defining: Yes RMS(α cos δ) = 0.2168 mas RMS(δ) = 0.2012 mas Cleaned No. sessions: 249 Cleaned RMS(α cos δ) = 0.1740 mas Cleaned RMS(δ) = 0.1604 mas

Note: Cleaning is a simple outlier elimination algorithm to remove bad sessions. Points whose distance to the mean scaled by the error is larger than 3 are iteratively deleted. The cleaned rms are provided as is and should be taken with some care, especially if the number of sessions is small.
