Right ascension: 89.8834713970838° Declination: 23.8983129794655° No. sessions: 832 No. delays: 18506 Defining: Yes RMS(α cos δ) = 0.2221 mas RMS(δ) = 0.3656 mas Cleaned No. sessions: 811 Cleaned RMS(α cos δ) = 0.1815 mas Cleaned RMS(δ) = 0.3170 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.
