Right ascension: 264.8641270185591° Declination: 49.9176022731020° No. sessions: 62 No. delays: 2297 Defining: Yes RMS(α cos δ) = 0.1901 mas RMS(δ) = 0.2303 mas Cleaned No. sessions: 58 Cleaned RMS(α cos δ) = 0.1785 mas Cleaned RMS(δ) = 0.2177 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.
