Right ascension: 292.8538200151369° Declination: 22.7253495784740° No. sessions: 137 No. delays: 6770 Defining: Yes RMS(α cos δ) = 8.5594 mas RMS(δ) = 0.5167 mas Cleaned No. sessions: 89 Cleaned RMS(α cos δ) = 0.1947 mas Cleaned RMS(δ) = 0.2805 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.
