Right ascension: 65.7175610670596° Declination: 2.3241474336383° No. sessions: 156 No. delays: 8704 Defining: No RMS(α cos δ) = 0.1912 mas RMS(δ) = 0.3408 mas Cleaned No. sessions: 137 Cleaned RMS(α cos δ) = 0.1616 mas Cleaned RMS(δ) = 0.1657 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.
