Right ascension: 320.9354892063963° Declination: 5.5894702570287° No. sessions: 1496 No. delays: 49322 Defining: No RMS(α cos δ) = 3.3697 mas RMS(δ) = 0.7748 mas Cleaned No. sessions: 1321 Cleaned RMS(α cos δ) = 0.2548 mas Cleaned RMS(δ) = 0.2924 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.
