Right ascension: 328.1034141470421° Declination: 17.5771652881589° No. sessions: 80 No. delays: 3166 Defining: Yes RMS(α cos δ) = 0.1724 mas RMS(δ) = 0.2593 mas Cleaned No. sessions: 75 Cleaned RMS(α cos δ) = 0.1535 mas Cleaned RMS(δ) = 0.2162 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.
