Right ascension: 248.1332077313749° Declination: 82.5378888272191° No. sessions: 234 No. delays: 7994 Defining: No RMS(α cos δ) = 0.2118 mas RMS(δ) = 0.1839 mas Cleaned No. sessions: 220 Cleaned RMS(α cos δ) = 0.1927 mas Cleaned RMS(δ) = 0.1609 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.
