Right ascension: 18.0242696748563° Declination: 22.7441073360660° No. sessions: 134 No. delays: 4847 Defining: Yes RMS(α cos δ) = 0.1961 mas RMS(δ) = 0.2464 mas Cleaned No. sessions: 128 Cleaned RMS(α cos δ) = 0.1520 mas Cleaned RMS(δ) = 0.2268 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.
