Right ascension: 280.6401736253273° Declination: 68.1570076829756° No. sessions: 77 No. delays: 6407 Defining: Yes RMS(α cos δ) = 0.1349 mas RMS(δ) = 0.1865 mas Cleaned No. sessions: 67 Cleaned RMS(α cos δ) = 0.1268 mas Cleaned RMS(δ) = 0.1608 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.
