Right ascension: 287.9927391781225° Declination: 16.1963514521058° No. sessions: 299 No. delays: 8185 Defining: No RMS(α cos δ) = 0.2959 mas RMS(δ) = 0.3083 mas Cleaned No. sessions: 285 Cleaned RMS(α cos δ) = 0.1711 mas Cleaned RMS(δ) = 0.2660 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.
