Right ascension: 287.4440112664581° Declination: 48.5755055833117° No. sessions: 21 No. delays: 628 Defining: No RMS(α cos δ) = 0.4256 mas RMS(δ) = 0.3034 mas Cleaned No. sessions: 21 Cleaned RMS(α cos δ) = 0.4256 mas Cleaned RMS(δ) = 0.3034 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.
