Right ascension: 126.4108841654809° Declination: 61.9579386934942° No. sessions: 17 No. delays: 1127 Defining: No RMS(α cos δ) = 0.2706 mas RMS(δ) = 0.1329 mas Cleaned No. sessions: 15 Cleaned RMS(α cos δ) = 0.2308 mas Cleaned RMS(δ) = 0.1305 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.
