Right ascension: 274.9391645353303° Declination: -55.3557626149386° No. sessions: 423 No. delays: 2197 Defining: Yes RMS(α cos δ) = 1.0142 mas RMS(δ) = 0.7104 mas Cleaned No. sessions: 397 Cleaned RMS(α cos δ) = 0.7950 mas Cleaned RMS(δ) = 0.5655 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.
