Right ascension: 291.4983556527187° Declination: 21.1072672028469° No. sessions: 1022 No. delays: 38435 Defining: No RMS(α cos δ) = 0.3184 mas RMS(δ) = 0.2220 mas Cleaned No. sessions: 930 Cleaned RMS(α cos δ) = 0.2207 mas Cleaned RMS(δ) = 0.1909 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.
