Right ascension: 343.2807048837294° Declination: 19.7096190741650° No. sessions: 153 No. delays: 5331 Defining: Yes RMS(α cos δ) = 0.1914 mas RMS(δ) = 0.2869 mas Cleaned No. sessions: 149 Cleaned RMS(α cos δ) = 0.1921 mas Cleaned RMS(δ) = 0.2760 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.
