Right ascension: 235.2062146414602° Declination: 14.7960790491446° No. sessions: 149 No. delays: 4976 Defining: No RMS(α cos δ) = 0.1918 mas RMS(δ) = 0.2202 mas Cleaned No. sessions: 140 Cleaned RMS(α cos δ) = 0.1602 mas Cleaned RMS(δ) = 0.1900 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.
